Very good point, but oxygen is very abundant and you’ll more than likely already have oxygen generators with a level of redundancy, or be in an atmosphere with oxygen.
Also for load balancing you could constantly be splitting water into hydrogen and oxygen, then react them back into water when you need a large amount of energy at once as an alternative to electrical batteries which degrades less over time, if heat is all you want at least.
All I’m saying is there’s so many applications that we’re never going to get to a level of 0.
Burning random stuff for heat requires cheap, abundant oxygen, though.
