It would be easy to agree with this but the only caveat is fiat creation by central banks and the potential for future fiat creation by central banks.  Frankly, I don't think anybody knows how this will affect markets going forward.  A deflationary collapse would have to be swift and powerful, which is definitely possible.  I believe we will see volatility increasing in fiat currencies with wild swings on both the deflationary and inflationary sides.  The aftermath will leave bitcoin and possibly a select few other chains emerge as dominant money and global finance and gold as a last resort backup storage of wealth imho.
