Agree. But that risk can be mitigated by using multiple mints and the ability to clear out to Lightning at a moment’s note. Also, by separating the mint operator from the service provider, it further mitigates a single point of failure risk.
In the end, this architecture makes a mint like a money router - if one goes down, you can easily switch. Finally there are some neat reputation services appearing like bitcoinmints.com and nostr.watch that’s where I discovered reliable relays and mints that I can use.
Sooner or later, an organization will stake their reputation on running a reliable mint and/or relay. When that time comes, we’ll be able to manage our risks accordingly.
