Only if you really don't like the idea of the Internet should you advocate for that kind of thing. If every website would have to comply with every country's laws this would immediately lead to almost complete segregation of the Internet. Why should anybody take the risks of making their websites internationally available? It's hard enough to ensure that your website complies with your own country's laws. It's impossible to do that for every country.

If a country doesn't like what a website provides they are free to block it at the border, just like with physical goods.
