Then it breaks and it is impossible to access your $150 worth of games.
That's just because everything hates you, as it should.
I've use Steam for around 5 years now and I have never had any problems with it at all, maybe it's because I've never tried to break any rules or piss anyone off like some arrogant starfish who just looks for trouble.
But oh well, not like it really matters.
On the subject at hand, ain't nothing wrong with wanting to buy an M rated game, but there's nothing wrong with them trying to uphold their own policies either.
Maybe you should stop being a spoilt brat and learn to accept that rules exist for a reason.
