You said in an earlier reply to mine that the masternode threshold was "too high" for you. But you must acknowledge that that threshold (in terms of financial cost) has been set by the market, not by the blockchain designers. The 1000 Dash is arbitrary and there for a purpose (to mitigate the propensity to sybil attack the network). The market then puts a dollar price on that and if the asset is in demand that price will rise which was the objective of the whole plan in the first place. That fact alone should mitigate some of your concerns about "sustainability".

Now lets wind forward a bit. It's 2020, the credit markets have imploded, cash got banned, the crypto-sphere is gigantic and there are a myriad of cryptocurrency asset types out there all serving different types of currency market.

Dash's marketcap is not one of the leading ones, just the size of a moderate internet stock today - let's say LinkedIn at $15B which is only 1 twentieth of Facebook's.

That would value the collateral for a single masternode at around $2.5 million dollars and the associated revenue stream at between a $100,000 and a quarter of a million dollars per year depending on emission rates at that time. Thousands of investors benefit from a masternode revenue stream and also from second level business models like the one described in one of the current blockchain budget proposals but none of them hold anywhere near the full collateral themselves, they are simply invested in all kinds of trusts and share products which are capitalised using Dash as their base asset. Furthermore, anyone who DOES actually hold Dash themselves in any quantity is quids-in because although their holding may not contribute to an active collateral base itself, it doesn't matter. It carries exactly the same value as the parts of the coin supply that do due to being in demand for either masternode collateral or trading currency.

It's all relative. We can't take today's values and project them onto tomorrow. The barrier to entry is 1 Dash right now and that gives you a theoretical 0.1% of masternode collateral which is how your holding will be valued, whether it's actually collateralising a node or simply decorating your wallet.

Masternodes are a great innovation in crypto. They solve lots of problems and add value at the same time. Hey, I think the barrier to entry on a Falcon 7X is too high and those things can't even be sybil attacked !@!  

 I absolutely love that roundtable video thingy. It only shows the world what they're about. They're absolutely clueless about what they're doing, and this is perfect promo on what not to invest time, energy and much less money in.

 Brilliant - they troll themselves - I't priceless.

I'm trying to understand what do you mean by that.

This is just something Kristov Atlas raised on facebook talking to Juan presentation in Anarchapulco. It shows just how mindless they are, just like them repeating Peter Todd about dash. Empty brains with no original criticism or ideas 

Bruce Fenton summed up this entire video perfectly when he says "So, you're a journalist who doesn't know anything about journalism." Nothing to see here, folks!

 45%, but in any case that is your opinion. Miners are not locked in a cage for their forced labour. They're perfectly free to mine whatever they like. Nothing is "ceded" anywhere, it is Dash's economic model, which has obviously proven to be working just fine.
 
 So what is your point exactly?

what are the reputable shared mn services?

One of the best is splawik21 with his https://dashtalk.org/threads/splawik-s-super-shares-service.3195/

...and yet the price remains remarkably stable.

Why is that?

Maybe because the already dead horse has been beaten, skinned, sliced, diced, and had it's bones run through a wood chipper.

No one is listening to the same old BS. True investors do their research, they don't listen to rambling fools with a YouTube account.
