All that benefit just from the simple fact that N2 molecules are bigger than O2 and leak out slower.

If you read the original post you will see why this unicorn excretion.
1, if you dont get the nitrogen fill for free like when you buy a set of tires they charge you $20 or more.
2, the nitrogen tire pushing web sites claim an you will receive an instant 20% increase in fuel economy.
3 the nitrogen tire pusher sites claim nitrogen defies the laws of physics by being unable to leak through rubber and that it doesnt change pressure at different temperatures.
4 The worst and most dangerous of all the nitrogen tire pushers sell false sense of security by making it seem like nitrogen tires do not require pressure checks.
That is why it is in the corral. Because its being sold by some as a magic bullet..
Now if you took a statistical sample size of vehicles, say a few thousand compared a group with nitrogen tires to a group with air, yes I bet you could see a slight fuel economy improvement and over all reduction in the number of tire failures with the nitrogen group.
