Hayek argued that the market would effectively govern such an economy and prevent both inflation and deflation. I don't know whether he was right; possibly we'll find out by experiment.
Eventually they will. You’ll have assets in billions of denominations, and you’ll be able to pay for coffee with a bunch of fractions of pennies and the markets will clear and consolidate value for you.
The future is not Bitcoin replacing the dollar. The future is the idea of a dollar replacing the dollar.
For all the other discussion topics, this is one of the most interesting aspects of crypto-economics for me. We can bake in different economic models and see how they work without it being easy to manipulate them later.
It's sort of disappointing that most platforms I've seen are either going for a basic deflationary model (token emissions dwindle and stop) or a fairly flat inflationary one (every block produces 25 new MeatloafCoins forever).
There's a lot of research that could be done into "how much do we have to expand the token supply to correlate with increases in actual economic activity and attrition while keeping token values flat against real-world goods". Not by actually pegging the value with a backing fund or guaranteed redemption, but rather by a self-regulating algorithm.
There's an interesting rabbit hole there: Can we get a proxy value for "actual economic activity" by crunching the blockchain, or will we need externl information feeds? Can it be made resilient enough to reject trying to game the system?
And then, there's the matter of "does anyone want to botstrap a truly stable currency?" Would you get many early participants if you say "it's explicitly designed to discourage speculative HODL behaviour?"
Value has changed a lot, but that was expected too. There are stable broad trends. Seeing the stability is just a matter of seeing timescales.
I guess I don’t share your definition of chaos. Chaos means you can’t predict anything reliably. You can predict many things about Bitcoin.
Taken to the extreme, your comment seems to come from a “anything that’s not a US treasury bond is total chaos” viewpoint. But I know that’s not what you intended... perhaps you can clarify?
Once these currencies hit their natural scale we will see some stabilize.
Exchange rates between them. Middlemen to pay to perform exchanges before you can actually use the currency to buy something. That doesn't immediately sound worse to you?
