That’s not what I meant. It’s hard to compare these two problems because one is effectively solved (table saw) and one is not (social media).
Of course the trick is that social media access doesn't require folks to pay an upfront cost, so it's harder to slap the cost of this additional service on the transaction. But of course as financial regulation makes banks do KYC and file SARs (suspicious activity report) social media regulations could do something similar. (Hurray more surveillance saves the day!)
Also, seems like an odd gating criteria for whether or not people support the idea of regulating social media (i.e. per the specific thrust of the original question).
