1 BTC = $1 would be nice, at least for people used to dealing in $US.
Similar to how CAD, AUD, NZD plug along at close to par values.
And difficulty about 1/4 what it is now.
What matters is that people see a need to transact in BTC, that it provides something that they can't get with the banking system - the ability to quietly exchange money without being "watched", without needing approval to open an account, to trade without being managed, out from under the thumb of a gangster/bankster mafia.
If the majority would wake up and take hold of their future they could break free of the oppression and terraform a new economic reality. Hooooowl. Is that enough of a rally cry...
How could bitcoin thrive at 1 dollar? That doesn't give 10000 people enough for a small house or everyone in the US enough for one meal. Bitcoin is a little toy at $1.
...What?
You want the price to be like $100/BTC with 10,000 people? We only have like 50,000 users or something.
I'm not sure what you're suggesting. Is a dollar at little toy at...$1? I assume you're suggesting that 21,000,000 coins spread among a population of ~7 billion would be pointless if they are worth $1 each.
The point is that if 7 billion people are using BTC there won't be a fiat/BTC conversion rate. If BTC is used by so many people, deflation would have long ago kicked in.
Or, another way to look at it would be that if BTC was worth a dollar (but still accepted by everyone), the same dollar today would be worth thousands then.
But, I must say you allude to a very interesting point. That point can be phrased as a question: How do we build a large economy if people can't buy houses? The housing example is a good one because there simply cannot be enough coins in existence to support everyone buying their houses, cars, etc. in BTC if it's worth $1. This isn't even close to being feasible at it's current exchange rate or even $30. And yet, even on this forum we see things like people selling businesses and gemstones that cost like 20 grand. Nobody should have that many BTC unless they paid for them with cash. Too few people with too many BTC.
So, we need to learn from the implications of this.
1.) Don't start out worrying about whether or you can buy a huge house or a car with BTC. It needs to start small. If the current supply-to-value ratio of BTC wouldn't support everyone in the whole world buying the same product as you intend to purchase, then you shouldn't buy it anyway.
2.) This means that you need interest. Interest comes from desire. Peoples' desires include wanting to be safe and connected, so focus on that. Security and ease of connectivity need to be of primary focus. Security basically comes down to having your BTC insured so you don't have to worry about your account getting hacked.
3.) Ease of connectivity means we need coders who will actually make the Bitcoin client easy to use -- and I said easy as in easy for a kindergartener to understand and use. Something like "Download?" And after the download, you now have the client, a miner (preconfigured), an account at a pool, and an account at an exchange. And maybe like a hotline number to call. How about a Bitcoin business where it is the job of the employees to simply explain the whole goddamn thing to people?
4.) If and when interest grows such that deflation truly sets in, you will finally be ready to think about purchasing houses and cars. By that time, you will also be able to make all the repairs on your house and buy all the tools to do them with BTC.
There is a serious flaw with any currency (or in any economy) in which a very small number of people hold a great % the currency. This is one reason I hate SC and it's dipshit spokesman. But right now I suspect a very number of people hold at least 50% of BTC. There's not nearly enough volume on the exchanges to explain the distribution of all 7 million+ BTC.
