I agree with your first point - but Meta and other organizations don't really have to act in a socially acceptable manner at their scale. Creating laws at least opens the door to legal action to keep them in line.

My last two bullets intentionally walked the line on stalking and spoke to some of the arguments law enforcement have attempted to use to nefariously surveil the public without a warrant [0].

I also have a difficult time jamming 'right to forget' through the first amendment protections in the United States but it does provide some protection/agency to individuals to protect their identity.
