lets interject my thoughts on that debate you two are having.
did you just say that? i am so facepalming that

onchain sole privkey control is a step towards the death of custodial bankers.
LN uses multisig. its literally the definition of custodial so multiig is a step towards custodial bankers
LN cannot scale as a hop and spoke model. and will requre hubs (bank branches) so LN hubs are another step towards custodial banking
LN has fund locks, revocations. so CLTV/CSV/revokes are a step towards custodial banking

LN features are multiple steps towards custodial banking.

one thing you need to learn about banking is this. dont think of american banks as one computer holding 300million accounts.
think of it as 95,000 bank branches DISTRIBUTED in different towns. with an average 3,200 accounts per branch

now
swap "hub" for "bank branch"
swap "channel" for "account"
swap multisig countrpart for authoriser
swap hub authoriser for bank manager
swap "route" for "wire transer"
swap "LN" for "swift network"

any system that has a punishment for moving funds without someone elses consent is a banking system.. and is not what bitcoin was originally built for
