I would rather have the ability to do it rather than not on pure ideological grounds,furthermore not banning it incentivises transparency, you can see more of where the money is coming from for example in US democrats are funded by more aggregate donors.
Ah, yes, transparency. "I received 250000€ from Renault-Nissan. No particular reason no. They just really like me. We talked. Also please don't pay attention to my upcoming votes and law proposals".
Lobbying is corruption, and it's also pay to play. Noone gets anything good out of it.
Calling it corruption and outlawing it doesn't stop the power of money and elite circles, it rather prevents small aggregate firms from doing it and yes I would rather know if they received such donation from renault for same reason I would want to know if a climate study is funded by oil corp.
This doesn't make logical sense. Making something officially transparent doesn't do anything to prevent the closed door meetings that will inevitably always happen.
