This is quite a slippery slope. If I host a website in one country, I do not necessarily care where people access my website from. It is not like I actively provide a service to them - they just use internet (decentralised network) to access it. What if I publish a newspaper here, someone takes it where the contents are illegal, am I accountable?
There was a period a couple hundred years ago when it was all the rage internationally to write constitutions. Lots of countries got constitutions within a few decades, and almost no constitutions have been written since then. I wonder sometimes how the internet would be different if it were implemented in an era or culture in which people believed in that sort of thing.
That is in essence already in place just for CSAM. We just pretend the internet is a free for all in all other cases.
