I apparently don't have the will power to stop going on these sites so maybe stopping me loading content from the other side is exactly what I need.

They already make demands.
Two of the very large national banks I have accounts with restrict your access if you're not even using the right browser version. One puts a warning in every page. The other won't even let you log in.
To make the second one even worse, it requires a very specific version, not just > $version, so if i update my OS too quickly, it won't let me in.
