"my country does barely have any contracts with other countries for crimes like this. So they would have to use a complicated way to actually force them to give out my data."

As far as you know. And that's exactly where the problem lies. You are trusting your adversaries to be honest about who they cooperate with, which is a great way to get screwed over, because your adversaries are adversaries.

So no, it still wouldn't necessarily be "better than not using one". The tradeoff is far more complex than that.
