It's only natural - as soon as you have heavy regulation there, all the processes become very complex and time consuming, as anything involving the bureaucracy is. And people with certain inclinations very quickly learn to exploit this. You want to evict me? Fine, welcome to the 2-year process which will consume immense amount of time and mental energy, while I live in your house for free in the meantime (and maybe destroy it - if you want to go after me for that, see above). Or you pay me off and we part as friends.
