Well, to be fair, I would also be in favor of banning lobbying entirely, which I recognize is also problematic - then you have laws being written based on sub rosa back room deals, since lobbying is to a certain degree "human relationships in the context of power dynamics" aka politics.
Banning lobbying would be effectively a ban on all political speech. Because that's what lobbying is: political speech. For example, yesterday I sent a bunch of letters to my elected politicians talking about the Rio Grande Plan[0]. That makes me a Rio Grande Plan lobbyist. Louis Rossmann spent several years traveling across-country to speak about right-to-repair[1] laws. That makes him a right-to-repair lobbyist.
What we actually are angry about is the presence of money in politics. American political campaigns burn money like nothing else, which is akin to being in a government meeting where everyone is shouting over one another, like to the point where people are bringing in loudspeakers and megaphones. If that example were a real situation, it would be entirely legal to go and have police officers take away the megaphones, and tell people to quiet down and take their turn.
But because money is involved, SCOTUS says that, no, shouting over everyone else with a big pile of cash is TOTALLY protected speech. Any money at all that is to effect political speech is inherently protected. And so we have campaign seasons that burn billions of dollars, and people who are basically not listened to, because all the anti-bribery law that was supposed to stop the election fundraising arms race got thrown out over a decade ago.
