Regulating a physical product being sold within the country, like a circular saw, is obviously materially different from enforcing age restrictions or other regulations to a website probably owned by a multinational company.

Personally, I don't have much of an opinion around circular saws, but I don't want my government to build a framework where they can choose to hide certain parts of the Internet. I also think the issue isn't social media, per se, but algorithms that promote negative content, personal data harvesting, etc. Banning tiktok et al isn't going to solve those problems. They'll still exist because other types of sites are implementing them.
