> political pressure. Same reason lots of stuff is banned in the EU even when it's safer than other things that aren't banned.

You avoid the question instead of answering it (What caused that "political pressure"? Does such a thing just occur randomly in nature?), following it by an assertion that you don't bother to provide any evidence for.

I believe the EU tends to follow a precautionary principle, namely a substance generally must be shown to be safe before it’s approved. In contrast, the US follows a risk-based approach where a substance can often be used unless it’s shown to be harmful. So it isn't really that many "safe" things in the EU are banned, rather they have not been approved. Pretty sure this is specific to food additives, though may apply to other areas.
