In most countries, extradition requires that you’re being charged with a crime in another country with something for which you could also be charged in your current country, and which carries a one year prison sentence. If you’re not breaking the law in America, you have nothing to worry about. (This is at least the case for the UK-US treaty - I’ve not verified for other treaties, but I’d highly doubt the US would agree to a treaty with anyone which requires them to extradite anyone for something that isn’t a crime in the US.) Of course, if you ignore the EU repeatedly, you’re going to be stuck if you ever want to expand to the EU, or have any assets there ever. That’s about all they can do.
