I'm the incumbent business in some area, I lobby for regulations that I can afford to pay, but makes it too expensive for potential competitors to get into the business.

I doubt you vocalize your goal of driving competitors out of business when lobbying for some new regulation.

You don't personally enact regulations... those who do are the ones with the good intentions. To them, the regulations seem sensible and net-good... no matter how misguided it might happen to be.
