Questions you should ask yourself.
How do coinjon like whirpool feel about these rates? 0.1 btc with ten entries in the 5m sats pool costs you just over 450k sats, something like 4.53%.
Why do you keep denying the need for layer 2 solutions?
Why are you so stubborn that you keep ignoring the privacy bonuses for the sender in Ligthning?
Why do you refuse to use Liquid?
Why do you deny the privacy obtained in Liquid by performing simple peg-in and peg-out (and especially if you use sideswap) which are much cheaper than a coinjoin?
These are questions you should ask yourself.
In the world survives the one who adapts.
