I’m considering the same thing you are doing… but want to think through the implications of it all, which so where my mind has been spinning the past week around this all.

I’m more thinking about later 2/3 applications of Bitcoin… not the layer 1 fungibility. 

Though the “making every tx a coinjoin” idea is interesting… however isn’t that what a lot of privacy crypto already does (and why they fall afoul..)?

Anonymity in Bitcoin...

You're describing a breakdown of the inherently delicate fungibility of bitcoin (having different flavors of bitcoin). 

We should strive to keep bitcoin as fungible as possible. Tools like e.g. CoinSwap could strenghten on-chain fungibility. Some are advocating for making every tx a coinjoin, to force fungibility that way.

I keep my KYC bitcoin in cold storage as such, and am slowly building a smaller KYC-free stack alongside it. 

Your thoughts are not far fetched at all, so we should heavily support further privacy projects. CoinSwaps could unnoticeably destroy deterministic links, so I'm closely following that project. 

Interesting times for sure...
