Thought it's about currency scarcity, which actually makes both small and big investors in deflationary cryptocurrency have more to spend on things they need.
In regards to the scarcity of basic goods and services, that typically results from not producing enough of the basic goods and services to meet demand. And this could also cause their prices to increase. I think people should use the money they earn to produce more rather just consuming. A society could alternatively (or in combination with the self help) invest more in the production/producers that's based on merit. Producers could be scored based on how fast they can produce good things without compromising on safety standards. You reward the best with more temporal lands, equipments, funds etc to produce more. I would invest more in medium/small-scale producers who are good at what they do.  You could easily get them to follow the reasonable health safety rules. Those who are reckless may even work under those who are cautious & good at what they do, to learn how to produce the right way without compromising on safety standards

A big problem if one country is not prepared for the future.
The pandemic came and most leaders didn't even know what to do. Close the airports and lose tourism but with the risk of getting the sickness from a different country.
Then there is the lower class that lost their jobs with businesses closing to avoid scattering the sickness. (not a necessity business)
Scarcity just as you said is also because of that reason. They are not letting businesses run in full swing to avoid employees from physical contact.
It's the sad truth but all we can do is wait and survive until everything goes back to normal.

I find it a big problem as well that the supply chain management changed the world so much. Companies are afraid to do inventory, everything needs to be done just in time. There is no room for error. In the food industry it is the most dangerous. What if we have 1 year of bad crops with only 20% return compared to the average yield? This is very dangerous. We can already see the problems right now in Africa and south America. I read in an article that in Brazil 1 out 6 people don't have enough food right now. That is terrible, we should do better.

watching the news all the time will help you see how these trade wars are going to affect economies. the grocery stores normally is filled with unlimited products but today there are stores that has empty shelves. scarcity of toilet papers was the first to be reported when pandemic started.

there is actually a token project that tries to solve  Supply Chain Management (SCM) and thats Vechain (VET). i have no updated information about the project but their token is pretty bullish.

Due to the pandemic the demand for food products increased a lot, and certain products faced down as well which means that people stacking the food products more than what they needed due to the fear of lockdown which is what we saw exactly in 2020 in many countries.

But do these issue still exists?

Scarcity is not an issue created in vacuum but it is created by humans and especially those in government. The government has all it takes to create a well developed supply chain but because they lack proper planning (especially less developed countries), then scarcity will be created. For example, when talking about demand and supply, you need good roads, proper communication levels or good internet connection. All these are important to get supplies down to final consumer. As to the cryptocurrency, it has taken the advantage of modern life. The digital is creating a good value chain through the blockchain and it makes life easier.

It has been said many times, but scarcity is inevitable especially for people who are clinging to go to cities where the cost of living is very much expensive and all of the sources are generally imported from different countries.

The problem is, countries and their governments find it hard to manage the sources because we all know that all of the countries are having hard times managing their own supplies, as well.

Well then, I think we should start digging holes and planting seeds that we will then soon eat. Scarcity has been there since day one. But we all have to survive and not blame anyone for it.

The lockdown almost made people unable to work and feed properly until it was lifted early last year where I live.
I would be surprised to see people go hungry or starve with no major crisis to cause that. Lots of staple Foods produce by local farmers are pretty cheap and not lacking in supply. If you want to hear about huge inflation, hunger and starvation happening around you, listen to the News. They seem to like reporting such things even when everyone is busy working, feeding themselves and not begging for food. You see very few beggers once in a while... If you ask even those making alot of money in your presence about the economy, they'll likely tell you they need money or there is no money anywhere.

They media tend to bring hopelessness to situations and does encourage society/people to greedy, unthankful, always complaining, even those that have enough.
Bees, ants and others animals are hardly seen dying of hunger in the midst of plenty. They have been working hard and feeding themselves, why not humans?

What exactly do you mean by "artificial food"? Yes, there are new technologies, that allow you to grow crops in artificial conditions, not depending on the season, there are even recent developments that allow you to create artificial meat of some sort.
However, though it gives us some freedom in terms of time frames, conditions, and these technologies can be adjusted to pandemic more easily, all of them still require some resources: light (which requires energy, which is, if not solar, still limited), culturing media, reagents for the technologies.
Nothing can be created out of the thin air and the key here is managing the supplies properly, ideally, by implementing recycling technologies, IMO.

Please tell me one thing that is scarce these days? Except obviously medical supplies in third world countries everything is readily available. It's actually the purchasing power or the incomes of the people that has gone Pretty down. I don't think any other currency would have been able to save us from this due to disruption in the economic system due to covid. So it is entirely wrong to say that there is scarcity infact the fed ensured that there is no limitation to supply so they printed a lot of money.
