Having more bitcoiners is worst if it means changes in the base layer or losing decentralisation.
Auditing the base layer and enforcing the supply cap is more important than more privacy.

Bunch of wrong assumptions here :
I said more bitcoiners not more ETF holders. More bitcoiners is by definition more decentralization.
Privacy solutions do not necessarily entail supply cap obfuscation. For example : coinjoin, payjoin etc...
OK I thought you meant we need 8B people on the base layer.
Most people in 25 years will hold bitcoin on layer 2 and that is ok
