I am not up to date with more recent efforts, and I have an intuition grounded in years of experience that tells me the lack of privacy and anonymity in L1 is going to negatively impact Bitcoin's use as freedom tech even when other layers do possess those properties.

Having said that, I applaud, support and commend any and all efforts to make Bitcoin more private and anonymous. I save in Bitcoin, as long as I have trustless a way in and out from whatever it is that I can spend privately with (Monero and Lightning at the moment), I am happy.

I am also fairly sure that this is not going to be solved with just tech. Many here eschew politics, I don't like it myself, but the fact is, our opponents organize against us using politics as a weapon, with the backing of the violence of the State once their surveillance becomes law.

Perhaps at some point the right answer is for us to organize politically and internationally as well. Or things will probably just keep sliding into tyranny.
