We could also teach basic computer literacy in schools so people could understand common scams. We could sell phones with "extra protections" that people with less knowledge could buy.
The only reason to force this crap on everyone is control. What google cares about is getting rid of people's ability to block ads, kill youtube vanced, and so on.
Google will implement this, the consumers will pay for it, scams will still exist, and Google will open their hands and say "welp we tried". The infrastructure will already be in place, and it will never be revoked.
