Points 1&2- yeah custodians can rug you, this can happen with literally anything(yes with XMR)
Points 3&5- if you cheat, your channel peer gets compensation. If they cheat and you don't catch them for 2 WEEKS using a lightning wallet, watchtower, lightning node software, yes you got your money stolen. That seems reasonable because if you do catch them they risk node access, all of their channel funds, and reputation.
Point 4- yeah, don't let people use your computer and route over tor.
Yes, I conceded that if you try to steal your peer's funds, you DO lose your funds. My bad, I should have stated that caveat.
lol, and again, read the thread. some force closed channels were returned to their on chain address. the other 4 channels in question were still open and active channels that were later collaboratively closed. and a nice telegram scammer to throw into the mix. no funds were lost.
did you read the thread or just the headline? no funds were lost. they returned to the on chain address when the channel force-closed. (By the way Alby was a custodial node service so, not a great example of a sovereign use of lightning.)
Ok, I didn't read the whole thing on the alby one but waiting 14 days for your funds to return to you is a bit ridiculous isn't it?
I mean conventional banking only takes 3 to 5 days, so in the mean time onchain liquidity is frozen up waiting for lightning to resolve itself.
Personally, I enjoy on-chain.
Force-closes are extreme circumstances. and the HTLC has a lock to avoid scams. giving someone 2 weeks to see they were being cheated is a feature not a bug. in most cases the collaborative close is used and you get on chain funds as soon as the txn is confirmed. it would be much quicker if threat actors weren't a concern in the real world. having the entire financial record on chain at the rate cash or credit is used would need storage the size of a Colosseum to verify. keeping rapid transactions off chain for velocity and on chain for settlement is the best way to keep a system decentralized.
