Do you seriously believe that is not happening now? Or that even a libertarian utopia could manage to achieve agreement?

If you're going to get philosophical, go all the way. Why have society at all because it's just people imposing their will on others? Or do you at least agree that there exists a line?

Even though there clearly must be a line on some topics, many people think those lines should be placed to minimize the number of times people are forced to do something (or prevented from doing something) against their will.

It’s not at all obvious that “adults can’t have TikTok” is anywhere near the correct side of that line.
