Maybe I'm misunderstanding what you meant by "über capitalist", but someone who advocates for total state ownership over food production (which is essentially what you're arguing for, given that you don't want profits) is certainly on the socialist/communist side of most countries' political spectrums, and therefore can hardly be called an "über capitalist".
I think it is entirely reasonable to tax or even heavily tax private property and profits so that we can supply necessary water, food and shelter to all of the population.
Reasonable amount of water and food should be in reach of every citizen. Does not mean production of those have to be privatized, but maybe margins can be limited when it is bought from open market.
