That’s actually how it works? Unless you have an extradition agreement, or military overmatch, or you are willing to expend some diplomatic leverage, you are typically not getting a citizen out of a foreign country. The government complains about this all the time with goods from SE Asia, and sometimes they seize fake designer goods and make a lot of noise about it. But the people making the knockoffs just keep on making them, don’t they?
just because a law is difficult to enforce doesn't make it not exist. There are laws for this, and they are enforced. If you aint caught its not illegal?
Typically one-sided laws are not enforced against citizens of foreign countries except in rare cases, because it creates diplomatic friction. Countries really don’t like it when you arrest their citizens for things that aren’t illegal at home. And when one country has enormous leverage over another, it’s a bad idea for the less powerful country to attempt enforcement. A visa ban would usually be a more appropriate tactic.
