No, that doesn't address the incentives that cause all those things: maximizing engagement to maximize ad impressions for money. You have to choke the money supply off at the source or the big corporations will just find other engagement mechanisms to hook users to get at more profits.

Instead, tax ad impressions per day per user on a sliding scale that makes it quickly unprofitable to display more than a handful of ads and use the money to fund media literacy classes in schools. Restrict the number and types of advertising that can be shown to children and adolescents, like forbidding animated ads.
