Could. How to eliminate it?

Maybe if there's a spec to coinjoin with any user-selected coordinator?

💯

This is understandable, but to an extent perfect can be the enemy of good.

For someone who just wants to save & spend directly from their main stack this makes a ton of sense.

I also think it's a nice part of a multisig quorum.

You can get a Trezor one & a Seedsigner for a multivendor multisig putting that cost at under 200$ is world class bang for your buck.

There's no trust required, Trezor's coinjoin account uses Tor and compact block filters so your IP address and xpub address are not shared with them.
