> Everyone complains about professional lobbying that they don’t like.
I think you picked the laziest understanding of both the issue and my answer, and made my point in the process.
I'm not talking about you paying someone to represent your ideas to lawmakers, regulators, judges, etc. but about paying those people to directly enact your interests. They're both big problems in their own way. Straight up buying laws or legal decisions happens even if the incentives move from the interest groups to the decision factors through so many lobbying laundromats that they look completely clean and disconnected.
The other problem is not better. As you confirm, real representation in democracy is not with your vote but your donation power. Even when your chosen lobbyist isn't buying anything directly, just having a voice and representation takes money rather than a vote. The EFF or Louis Rossmann have to struggle so much to be heard because other people pay more to be louder. If you have problems being heard for money, imagine the people hoping to be heard for free.
The large majority of people can only spend one vote every few years to choose a representation that a small minority will spend a lot of money to hijack: either drown out everyone else's voice, or directly purchase exactly what they want. If you can't see why "everyone complains" maybe you're too disconnected from the problem to even understand it.
