There are two major problems with this.
The first is that you don't actually know which countries you have to avoid. There isn't going to be an app that can walk you through every law in every country.
And the second is that you're not the one flying the plane. You thought you were going to Charles de Gaulle but the weather in Paris is worse than expected or some drunk driver crashed the gate and drove out onto the runway and they're diverting all the planes, so after you're already in the air you find out you're actually going to Heathrow.

They already do stuff like this. The fact that they do it is now being used as a justification for doing it more and elsewhere. You can watch people telling you that slippery slope is a fallacy as they're greasing the hill.
