Yes, remixes are free but because of that there are too many UTXOs competing to be remixed.
It took several MONTHS for me to get 10 UTXOs to five mixes.

Whirlpool may be slower than competitors to get the same anonset but the slowness is a feature because it introduces Sybil resistance.
I don’t buy it. Requiring the user to leave their PC running 24/7 for a few weeks is not a feature. Most users will not wait that long and simply accept fewer remixes thus lowering the effective anonymity.
UX has to be considered and what you describe cannot possibly be a feature.
Yeah.
FYI, Wasabi has a successful coinjoin every 15-30 minutes currently, you can join whenever you like.
A decent level of privacy is possible after only a couple hours.
