If Facebook were at all a force for good in this world, maybe I'd agree with you. But given the litany of other social ills they are directly or indirectly responsible for, I'm fairly confident you could nuke them tomorrow and the world would be a better place.
"Don't bother enforcing laws because people try to break them" is an express ticket to a Mad Max world. It's also not a particularly interesting or practical solution, and honestly comes off as a little disingenuous.
We know how to pretty effectively police roads, but a surprising number of people here seem to think that any amount of internet regulation is impossible. If it's so harmful _and also_ difficult to police, then it's not unreasonable to ask how much death and destruction is too much, is it?
Unless, of course, "it's so hard to regulate" is just a thought-terminating cliché because the SV set also benefits from lax internet laws. But I'm sure it can't be that, no...
