"We can't get rid of this toxic part of society because what if people lose jobs?" has never really been a great argument. Like, maybe society could find a way to financially support people who transition to a new career (although if you've made any sort of money from ads, I'd argue that uh... you should've saved more, but whatever. Labor rights, etc.). "We ban something and then you're just out of a job" doesn't have to be what happens, it's just what typically happens. We can get creative, though! Other modes of governing society are entirely possible. We can both support people and keep them happy and healthy, while also getting rid of things like advertising. We just need to imagine a better world.
