the base layer has pseudonymity already, it's just wallets that have to be fixed.
they will certainly be going after that, as well as trying to attack protocol changes that would make privacy easier to do. it still can be done.
also, you obviously must realise that mozilla's "protecting your privacy" and the tor project also were long ago compromised. and maybe you are aware of the suspicious circumstances around the death of Ian Murdoch, the cofounder of the Debian linux distro. i also wonder about the case of Hans Reiser as well having dirty tricks involved.
for example, why did Taproot not include a proper single-payer P2PKH for the out points? if you do a big payment with them you have revealed your public key which means quantum attacks can then have plenty of time to try and break it. or for that matter, the lack of sane protocol limits on Taproot push commands, which opened up witness data, which is cheaper, to spam.
all of it smells, to me.
