This is again, wrong. EULA is just another word for "contract", and I'm not aware of any countries that have banned contracts.

Of course, specific EULAs may not be enforceable in some countries because they contain terms prohibited by law. But the concept of EULAs - a contract where you agree to certain terms in exchange for license to use software is enforceable in basically all countries.

IANAL, but the "A" is "agreement," which is only true if entered into. If I put a sentence at the top of my website that says "by loading this page you are agreeing to my terms of $1,000,000 per byte downloaded, payable by bitcoin" you are for sure not under any obligation that I can imagine because you didn't agree to my ~~terms~~ demand
