>they are not enforced ... widely, rigorously and thoroughly

That's a major source of the danger. If they were being consistently and equally enforced, then it would be obvious when there were issues. In the case with selective enforcement, the government can point to the law and say they're in the right, but only apply it when it suits them. This lets the people making the rules and the people who are in their good graces do what they'd like due to selective enforcement and not face the consequences of their actions.

Yes, like I said it does not excuse it, and for some laws especially those with severe punishment, it's a serious concern.

However in the case of certain types of policies it's not about intentional selectivity, it's about selectivity due to infeasibility, a type of selectivity that is not completely effective against any individual. For instance this one i'm pointing out: it's not possible to hold every single food source hostage in any country... but seriously, we are talking about food... in China... i'm running out of ellipses...
