How to increase max flight altitude above 500 m?

[Kilrah]

It is possible.

It wasn't at the time of that discussion.

 

[FlightGuru]

the question was technical and not legal.

(fyi, there are 200+ countries on Earth + intl airspace, and each country with ATC that could grant whatever altitude they want)

Not legal? What if he’s flying directly above a property he owns. Whenever you own property such as a house, you own the space directly below and above. Did you know that Mr. Legal? It’s people like you we have those limits…

That's an interesting concept but it's not correct.
