Pretty much every climate scientist disagrees with you. We can't avoid severe effects, but we can still choose between expensive horrible disasters, and the end of modern civilization. Lowering our carbon emissions by a large amount is the main way to do that.

Doing nothing but solar radiation management has serious downsides: it does nothing for ocean acidification, and if you ever stop pumping out that sulfur dioxide or whatever, all that pent-up warming hits you at once. I see it as a temporary emergency measure, to head off heat-driven feedback effects.
