We don't want people to keep stuffing in a bunch of useless things on the base layer either. More privacy can be reach on second layers. The #Bitcoin transparency is necessary for it's succes, thus "Proof of reserve", etc. And Base layer privacy introduce inflation bugs that requires even more devs fucking are around with it. There are work that need to be done like fixing the timestamp problem but we don't need billions to be donated to devs to stear #Bitcoin core in defferent directions either.
