My prescription: removal special consumption taxes from oil and gas, and disperse pulverized magnesium silicates in the troposphere. The energy cost of this pulverization and dispersal is small compared to the energy previously gained by putting up the CO2 the dustmotes take down. Without a special interest in continued fossil fuel burning, governments will no longer footdrag on conservation and substitutes.

let the baby light matches in the fuel storage room!

it is probably not yet, or not yet to the proper degree, being taken, and therefore can be labelled pie-in-the-sky.

How much mining will that involve? How much dust blocking sunlight and congesting lungs?

I'm sure no-one here believes I would propose this as a solution if those were serious concerns. Hint: the extra CO2 in the atmosphere is ~100 ppm. If we had to load the atmosphere up with enough dust to take that down, and only once the full load was up would the precipitation occur, that might be a little dusty. But in fact it doesn't have to stay up to work. More here.

What about all the other problems involved with the fantasy of unfettered consumption?

If you want to fetter the consumption, in particular, of fossil fuels, you will find the removal of consumption taxes on those fuels helpful. Speed limit enforcement, for instance, could again be as severe as it was in the 1940s; those charged with carrying it out would no longer understand that in so doing, they were impoverishing their paymaster.
