You haven't weighed the consequences enough: I can afford a modern home, I built one, well insulated, with a proper VMC+heat-pump, p.v. since here is a good enough option, all-electric for cooking and heating etc so yes, I can consume without produce extra pollution and potentially publish that like that very text here. Is exactly USELESS for the humanity because those who can afford are a small percentage of all humans, and such cohort below a certain age is mostly interesting in doing so or have already done that in the recent past while an older fraction is simply not interested due to their life expectancy. MOST other humans can't, wanting or not.
That means you suggest to push more and more people to poverty, generating unrest, repressions, dictatorships "to keep the society up", witch end up like in the first part of the '900 in nazi-fascist regimes the same polluter and criminals against humanity who fund them in the past fund the same move now.
A very simple example: WFH means I can work on a desktop. A desktop means a computer that can last 10+ years in relative comfort for 99% of jobs and be destined to such jobs when not enough anymore for more demanding activities like a new desktop for a child out of the parent now-dismissed "workstation-desktop". If I have a less wealthy life probably I can't use a desktop, I might get just a craptop able to last two years maximum from some company. An EV for me might be nice: not using it every days I can mostly recharge from solar so it might be cheap enough and protect against fuel shortage around my homes if/when they'll happen. Someone who use a car daily because he/she need can't. Those who cook with gas mostly do that because that's are the tools they have and can't afford buying new ones.
FLOSS is a must not for the Earth but for us humans, to preserve Democracy, to avoid a day being locked out of our home, having lost our third-private-party provided IDs, locked out from our car etc. FLOSS principles of development, witch means public research and public money, public code, are a must to evolve in a socially sustainable manner instead of funding very few humans interests against all others BUT no, increasing prices of polluting things people's depend on is NOT at ALL a solution, it's just a way to lend in a dictatorship with a polite justification.
If we want made a genocide of so many people to save the human species we need to be loud and clear, because we need to preserve "background noise" that made natural selection and evolution possible. The idea of classical eugenics is not less harmful nor a-scientific than the classic cross marriages between nobles not only for short-term political reasons but also to preserve the lineage "purity". We can't substitute nature effectively so we need to preserve diversity and natural selection, trying to generate and artificial one with various basis is a recipe to end up in a disaster large enough to have enough potential to crash our spaces.
