It's not entirely about enforcement. It's also to a huge part up to the person(s) holding the copyright in question. Suing individuals (maybe even in foreign jurisdictions) isn't a lot of fun or cheap. It's also a huge question what enforcement means in this context. Not being able to export your product obviously isn't great but it's not really scary either. There simply isn't much determent in "having to stop" violation x while violation a, b and c go unpunished or even just after having profited on x long enough to make it profitable to gamble on it.
