The laws were (presumably) debated before they were passed. So it's not premature to enforce those laws today. It's not shooting first and asking questions later. It's more like asking questions, having a vote on whether we can shoot, and then shooting.

We may not like the exact formulation of those laws. We may consider them overly broad or intrusive. We may feel they should have distinguished between abusive profiteers and average, well-intentioned citizens who only rarely rent out their apartments. These are reasonable positions, and I can see their merit. We probably should have that debate. And amendments to the existing laws probably should be given a fair shot in the legislature.

But until then, it's entirely appropriate to enforce the laws that were duly passed many years ago. One could argue that the government should exercise some discretion, and enforce the laws only against those operators who are actually causing a problem. Well, according to the unnamed source in the government, that's exactly what they're doing. You may choose to believe that source or not. But until we hear about the government coming down hard on a legit, small-time user, I'm prepared to give the government the benefit of the doubt on this one.
