Capitalism does need some regulation, as a true 100% free market would be anarchy.
Those regulations however should focus on things like safety, environmental protection, workers rights, and anti-trust protections.
They are unfortunately a necessary evil to bring some good sense to the greed.
But when regulations allow for cronyism and protectionism, that is when they become problematic. Or when they are too odious, broad, or poorly planned.
Regulations should be measured well and balanced in order to prevent doing more harm than good.
