Fungible isn't an all or nothing, again you can have a subset of the supply private and the rest public, just like you can have Monero moved to exchanges and public sidechains or wrapped tokens that are auditable and public.
So unless you want everyone on earth to make the same choices as you do, with their own money, their will never be 100% of the supply in perfect privacy that satisfies you
Anyways, you should sell all your bitcoin.
