I agree we shouldn't let people physically destroy internet infrastructure. I don't think this is controversial. I don't think we should regulate how people peacefully interact.
Violence is fundamentally preventable because people have agency in ways that animals do not. You'll note that only violence with knowledge is considered horrific. For instance, being attacked by a person with the mind of a 4 year old isn't considered nearly as bad as being attacked by an otherwise normal adult. The adult knew what they were doing and did it anyways.
> I see you've also added property rights now, which are a totally separate category from violence
I suppose it stems from the idea of natural rights - ie. what would you be able to do if there were no other people around? Would you be able to put something down and expect to find it where you put it? If so then you have "property rights": the reasonable expectation that your material activities will not be interfered with. The rest of it is mediating how your property rights interact with those of others.
Liberty is basically the idea that you should be able to do anything at all as long as it doesn't interfere with the rights of others to do the same. The legitimacy of government is derived from its defence of liberty. It's not about preventing "bad things".
- The internet is a common shared environment, so its maintenance should be regulated like other environments to manage externalities.
These points seem consistent with your philosophy and also permit regulation of social media companies.
