A single person shouldn't be able to block an airport that will serve millions. I get HN is very supportive of private property above all else, but not everyone thinks the individual comes before the millions of others involved.
By this logic it seems, there should be no individual rights whatsoever. Whatever is deemed by the State good for the many is therefore what shall happen. Am I reading this correctly?
US city planning history is replete with entire living neighborhoods getting bulldozed for highways and shopping malls, and the cities never recover their vibrancy.
If property rights were viewed as immutable as geography, cities would just have to make do. Either buy the owners out at the price they are willing to sell, or find other solutions. The idea of a private owner "blocking" something would never arise.
So, whatever is responsible for the lack of proper infrastructure, your explanation isn't correct.
So how many people should be able to block an airport extension? a hundred people, ten thousand people?
What you're arguing is the classic of the trolley dilemma [1], the individual vs the many. Should you harm 1 person to save 1 million. The difference here is that you're not killing the individual, you're demolishing their home, and you're not saving 1 million people, you're making travel a little more convenient.

As for the trolley dilemma, it's a great thought experiment precisely because people's answers and their reasons for their answers differ. I'm not sure therefore of its relevance here. Presumably the person you're responding to can just be consistent in their response to both the question about airports and the trolley dilemma.
Of course if that's genuinely the situation, it's hard to argue that the needs of the many shouldn't be paramount. But in the case of airport expansion, it's rarely that simple!
A bigger airport isn't necessarily a public good. If it's close to urban areas it's often a net detriment to the public good, inflicting more noise and pollution on millions of people. The drive to expand really comes from the airport operator's desire to increase flight numbers and profits.
“Society” can be quite cruel and inhumane to individuals, who need strong rights to protect themselves — including property rights.
