Thus any limitations that would prevent a large growth in adoption would also destroy most of the existing/stored value, since whenever "the market" would believe that the usage growth is going to stop, the price and the market capitalization would drastically decrease.
If you're talking about transactions-per-second, how could the market not already know that this is the case? Computers have finite resources, and a decentralized immutable proof-of-work ledger would be really inefficient to run on ten billion devices forever.
But if you mean growth in total perceived value, Bitcoin's use as a trust-less standard for floating other currencies could continue indefinitely. I'm not able to talk seriously about the proof-of-work/proof-of-stake argument, or the inflation/deflation argument, but there's no known technical reason that each Bitcoin can't be worth a trillion dollars in the far future. In addition to the economic and political theory, you're basically betting that asymmetric crypto, SHA, and the Bitcoin source are all mathematically sound, and probably that physics imposes serious limits on computing power, if you want to make that (super) long play.
The phrase "limiting flaw" would be less confusing.
As an aside, the phrase "rhetorical question" has a special meaning, but the adjective "rhetorical" just means anything relating to discussion. I was trying to say that you veered off into a meta-argument about the words we were using, which unfortunately I'm now continuing.
This is the flaw I was pointing at. Others have said that while there's some research there doesn't seem to be a solution for it. A cryptocurrency that scales it's size in rough proportion to its trading and thus keeps prices in check with maybe slight inflation would be interesting. It's almost surely difficult to accomplish given the restrictions in what you can do in a distributed consensus type of setup.
I'm not convinced it even matters though. Of all the important things we need solutions for in the world cryptocurrency doesn't seem to help any than I can see.
These already exist, with all kinds of incentive schemes and target inflation rates. If you're saying that deflationary Bitcoins can't possibly "win" in the long term, but something else could, I guess it's plausible and I don't know a lot about that.
I do know that Bitcoin was started partly in protest of inflationary Fed policy.
