Too many people are just replaying inflation discourse from the 1930s and 1970s over and over again in their head, talking up the imminent collapse of the dollar, without actually taking a look around.
The "shills" are not wrong. Every single currency that ever existed went to zero. The USD will be no exception. Honestly, BTC will be no exception either.
I can pay my non-imaginary taxes with dollars. All my other bills also helpfully accept dollars. This gives dollars a useful non-imaginary quality crypto does not have.
There's a handful of objectively valuable things like air, water, and food which I literally cannot live without. The value of pretty much anything else is imaginary because it's subjective.
The value of cryptocurrency is just far more imaginary than dollars, euros, or even gold.
Well, the USD is backed by the "full faith and credit of the United States government" which, however you may feel about it, isn't imaginary. Each dollar is a claim to a piece of output of the world's largest economy with the strongest military.
