I'd add to that list the option to vote "no confidence". About half of Americans do not vote, and I strongly suspect that for a large chunk of them it's because they feel there's no candidate which represents their interests.

And if the majority is "no confidence" we get a special runoff election with new candidates.

Until money and politics are commingled there will be no solution

I think you may mean disentangled?

Which is almost the same as saying "until money and power become disentangled", which is very unlikely to happen in our lifetimes (if at all).

Personally I think they’re inherently linked. How exactly would it look like for money and politics not to be linked? Money is political. There are some low hanging fruit though like corporate personhood and super pacs.

Start with public campaign financing, and saner election procedures. Primaries, caucuses, first last the post, and electoral college? It all contributes.
