My only objection is that the money is only as good as your internet. A more remote threat is the 51% attack (a majority of miners can coordinate to block transactions of a targeted key or keys).

What are your thoughts on non-internet implementations of Bitcoin?
Use gold. I think we need both. When internet is working, BTC is much easier to send across an ocean (or even across the US). However, gold keeps "working" regardless of internet. Even avoids "moth and rust doth corrupt", but still has the problem "where thieves break through and steal".
I have been imagining a Lightning network for gold. Maybe using existing Gold companies as custodial nodes.
