It's not a out how people spend their money so much as people having their options limited by existing monopolies. If people can't buy an alternative it doesn't mean there is no demand
I agree removing barriers / manipulations is good (stop oil subsidies, stop clean energy subsidies). Beyond that you’d be telling people how to spend their money.
No one is preventing solar companies from existing. Anyone is free to start an electric car company. There may be economic limitations to the tech but that is a different issue.
