Maybe it is you who wants politicians to regulate.
I want them disappeared as much as possible and that they work giving service to others, not f*cking the very pillars of the benefactors of our society, which are business that produce something useful, by taxing them and imposing obligation after obligation, and, when they are friends, giving them competitive advantage via regulations with excuses to protect this or that, absurd regulations that only have the incentive to exchange favors, making effectively non-viable ideas and business that could succeed and improve all people's lives and remove government handouts.
The people that should govern should be people specialized in the tasks they do, and those tasks vary, in my ideal world, from nothing to security + minimal laws (do not kill, do not harm).
All the rest is giving them reasons to accumulate power that only is misused to polarize people and to give advantages to friends.
We elect politicians to oversee government and make laws.
Anybody can 'lobby' them, we generally want that, because we want politicians to be informed and responsive.
We do have to be careful about undue influence, which is why we have rules for that.
