Isn’t the obvious leak here that the exchanges are cooperating with authorities and telling them time, amount and user details of every monero deposit/ withdrawal?
If the sender or receiver of a transaction shared details of the transaction with others, is not a failure of the protocol.
No it's not a failure of the protocol. But with that much centralised data flying around you want the protocol and the environment around it also protect against this as good as possible.
Not using any centralised banks is a good start, which is also true for all the big LN nodes that are all large banks.
it's not possible for every current and future monero user to cease using monero and take up a convoluted lightning setup. there's not enough room on L1 for them to all perform the necessary channel maintenance steps. there would have to be a blocksize increase, because lightning doesn't scale users. everything that was done to get around this problem results in total loss of sovereignty as well as increasing levels of information leakage.
this is just one of the many reasons why the mass conversion scenario envisioned by super testnet is not actually possible with lightning.
let's start with every current user, it's possible for them to do it
and if they do then perhaps the number of future monero users will be 0
