This is a good response, however you're missing the elephant in the room regarding Liquid vs Fedimints.
Liquid there is an audit-able supply of tokens. The blinded transactions hide the amount being transacted (and who holds what). However you still have visibility of total supply of said token.

I think Cashu had something like proof of reserves, don't know if that can or will be used in fedimints. But yes it can be a problem i guess, at the end of the day your are always thrusting the guardians. Liquid is more transparent in that regard.

There are 3 main problems with Liquid:
  1. They rug all users pegged Bitcoin (unlikely)
  2. Possibility of them censoring your transactions
  3. Possibility of refusing Peg-Out
In practice I think 2 & 3 are the same problem....meaning if you could prevent them from censoring transactions, they couldn't stop you from pegging out (specifically, they wouldn't know who was pegging out therefore they wouldn't try to stop it).
Liquid, like BTC has no real concept if addresses are owned by same person or not. So a mitigation strategy to this is to immediately move funds from Peg-In to another address you control.
So (a) Peg-In Address --> (b) Initial L-BTC address --> (c) New L-BTC address
In theory, at that point, Federation members can no longer "know" that Address (c) is owned by same person that pegged in or not. Further, Federation members will no longer know what amounts are where.....
