The idea to inflate space foam reflective bubbles to reduce incoming sunlight is one of the saner geoengineering proposals:

* It can start small and grow to measure incremental effect,

* It's orthogonal to any unintended effects as it happens in isolation and isn't deeply coupled to things unknown in the same sense as aerosols and atmospheric chemistry is.

* It's reversable as bubbles can be popped and no longer exist to reflect and have an effect.

Yeah, on this we can agree- a high degree of global nation state consensus is what's called for with most climate action .. like the 1970s UN agreements that got effectively sunk by unending Koch et al oil bro's negative media campaigning and lobbying.

'Lone' capitalists do seem to have undue sway in matters that impact billions.

How would it be VC funded? Where would the return on investment hypothetically come from? If you could produce localised effects while being able to turn them on or off then maybe you could charge for it as a service, but is that at all realistic?
