In reality, this turns into we should have billion dollar handouts to narrow interests because rather than use taxpayer funds to R&D cures into the public domain using the existing world class university system, the narrow interests would prefer being able to benefit from patented medicines:

> Since August, U.S. or European health regulators have approved four new products intended as one-time treatments for rare genetic diseases that carry list prices of at least $2 million a patient, including two from Bluebird Bio Inc.

That's an extreme extrapolation. Sure, the majority would maybe not care at all for such a minority treatment if it came to pass. But then again, the practical reality is that in a system that allows minority to override the majority, everything else goes wrong even if that one goes right.

There is an example. The US was explicitly crafted as a format that would allow the minority to override the majority to prevent 'the tyranny of the majority'. This was explicitly expressed by various founding fathers of the US, especially by de facto architect of its constutition, John Adams. And that's the reason why there is FPTP, the Senate, the supreme court, with the latter two easily able to override whatever majority vote is.

They did this because they feared the majority demanding land redistribution and passing it with their vote. The British aristocrats' lands were confiscated and redistributed after the revolution, that was ok. But the founding fathers feared that it would give ideas to the people about the lands of the now-American-but-ex-British elite like themselves.
