Indeed, it's still not exactly clear what the right place of social media in society is. Perhaps we could even get rid of some of its pernicious aspects without throwing the baby out with the bathwater.

Even food is not unregulated! And not because too much food is bad for you, but because bad food can harm you.

A disanalogy with food is that there are natural limits to how much food you can/want to eat at one time. Another is that food is necessary for life. Neither is true of social media.
