This argument has been used in one form or another for eternity. We, the elite, are organising our system for your benefit, it keeps you alive, it feeds and clothes you, if we don't continue what we're doing you'll all suffer.

It's fallacious reasoning which seem to indicate you're actually then supporting the system that is causing the problem and you cannot see any alternative. That fallacy is that of "TINA" or a "false dilemma"

There must be a hundred ways of ensuring sufficient affordable housing, heating and food in any society. It's just that none of them are being investigated or planned presently.

There also appears to be a problem of a misattribution of blame. The "big ask" you mention is "volunteering cheerily to support an abstract idea" No, the big ask is accepting the system of control that brings them to this pass in the first place. It doesn't have to be anything to do with global warming, having enough food on the table comes to mind or obtaining health care in a timely and effective fashion. (Your opinion also seems to indicate a degree of climate scepticism but perhaps I'm reading too much into this?). .
