I'm not sure that's an apt comparison. rms simply has a workflow that doesn't require the use of proprietary software. It's not that inconvenient for him.
In on-topic comparison, it would be having a lifestyle where you'd simply have no use for a car: you live close to work, enjoy riding a bicycle, etc.
Of course, finding that workflow or lifestyle might limit some options, but once you accept that, it's not all that inconvenient.
I suppose so. More home cooking, sourcing ingredients, finding small markets, knowing the right restaurants, etc.

That's probably and unfortunately very true, in software as well as food and CO2 reduction.
A good comparison would be FOSS. Richard Stallman inconveniences himself to the point of absurdity, but I'm pretty sure barely anyone does anything close to it.
I changed my diet, I live in good housing, but when I put the numbers on paper, I'm not doing much at all, and could do much more.
