Each medium of wealth storage has tradeoffs, so being categorically opposed to one type because of ideological principles seems suboptimal to me.

For example, fiat may be subject to devaluation, but is stable, widely accepted, highly liquid and (cash) is anonymous.

Bitcoin is subject to speculation, so prices are highly volatile, amongst other downsides.

Land tends to maintain or grow in value, subject to interest rates, tax environment, and adjacent developments, and is very illiquid.
