You are of course not entitled to buy, as in general nobody is obliged to sell. If somebody should be forced to sell at a lower than their preferred price, the question is, by what rights should he be forced to do so? The government would effectively be stealing from that individual. By what rationale/right? As I said in another post, I personally did not get the benefit of a cheap place to rent in the center of Berlin. Why should I think other people have a right to it? You mention healthcare, but I don't think you can force physicians to work for an arbitrarily low fee. That's not how the system works in Germany, either. Public health insurance defines how much they are prepared to pay for things in the healthcare system. That is not the same as enforcing a maximum price. And especially with the German health care system, I'd argue that normal people have no idea of the actual upsides and downsides of the system. If there is a maximum price on health procedures, it means certain procedures won't be available. I've actually heard that there is already a health care tourism industry in Germany, which means the most skilled physicians might not be available for publicly insured people anymore, because they serve rich people from Saudi Arabia. Sure, in that sense it is bad for the normal people. On the other hand, highly skilled people might not even exist without high incentives, and in the end more people might decide to train to become highly skilled. Expensive machinery might be used for less solvent patients if there is a downtime. It's not so easy to claim benefits of limiting laws.
