Sorta, but not really.
There isn't a bitcoin <-> fiat system that will work well at $100,000 per bitcoin. However, there will be people who will trade this tractor, that farm land, that house, that car for bitcoin.

Also, at that time, the laws for crytpo = money will not be passed yet, so if you convert your crypto to dollars, you need to pay capital gains on them.

I feel the dollar will be failing, but it will still be holding on by a thread.
