Bitcoin is absolute mathmatical scarcity. Shitcoins can't rediscover that. That's why they don't work.
This is about trade offs, not purity tests.
WOS does not solve the double spending problem.
I think this is okay if you're talking about zapping and recieving 100k sats a month.
If you need more than that, use Phoenix and transfer your non-custodial sats every month.
I've also used custodial lightning addresses. Mine only worked about half the time. I've also lost at least a million sats breaking various nodes over the years. I also can no longer withdraw the sats I earned on yalls.org because of it.
It is my opinion that you can expect to lose more sats using self-sovereign lightning than by keeping small amounts of bitcoin on a custodial lightning service.
That doesn't mean I think you should use shitcoins or give your life savings to blackrock ir FTX.
