I see where you’re coming from, and I think this would be cause for concern if we had to give identifying information to these custodial lightning wallet, but I think there are real trade-offs when it comes to convenience.

Should you keep your 0.5 Bitcoin on Coinbase and trust them to hold your wealth? Absolutely not. You’re going to get rekt.

But if it’s coffee money, and the custodial wallet refuses to allow you to make the payment, then you have effectively lost a $5 bill out of your pocket. That wallet is going to get rekt when people realize they don’t have access to their $5, and another wallet will come around.

Not your keys, not your Bitcoin still applies 100% because you are not trusting the wallet to hold any real value that you don’t intend to spend anyway. If you’re willing to trade 20,000 sats for a cup of coffee, then you valued that coffee more than the 20,000 sats.
