If the rent is disconnected from the property value, then there is a speculative bubble.
If the rent goes up faster than wages, people become homeless.

If rent goes up faster than wages, which cannot go on forever, it means an imbalance between supply and demand. The best way to address this is to rebalance supply with demand, not to be tempted to control prices or whatnot that do not resolve the root cause.
It must also be accepted that the most sought-after areas will be the most expensive and probably out of the reach of many.
Edit: So much for mature discussions, I see...
In a free market (the UK is about as free a market as you get in relation to property ownership and rental), this might be true. But it does depend on how regulated the market is, in terms of rent controls etc. I'm not sure this would hold for an older, or bigger, or more difficult to maintain property in an area with a high percentage of renter competition in some European countries, for example (e.g. Germany).
It's the other way around that disconnects happen: rents stay the same and property prices go up.
But that's not why you got downvoted, no. You misunderstand price controls. It doesn't mean that everybody should have access to a nice apartment in a sought-after area. It means that I should have access to a nice apartment in a sought-after area.
Yes, that sums it nicely.
