Software and construction are not analogous. For one thing, no one is talking about regulation of social media that has to do with life and death matters. Are you proposing that no one should be allowed to create a video sharing platform unless they can prove in advance they can actively monitor all uploaded content, regardless of how popular they get?

You may not believe that if you live in Myanmar or Kenya. Large amounts of behavioral information in the hands of the wrong people can absolutely be a life or death issue.
I'm not saying there are no life and death matters, I'm saying no one is talking about regulation that would address them. I could be wrong, I'm not current regarding the relevance of Facebook and those countries.
