I understand why businesses would want to maximize work done in an area - I hope you're self-aware enough to realize this.

The tension you may be blind to, is that society wants to maximize safety in an area - and any work done should be in service to that goal, and not an end unto itself. We shouldn't blindly maximize for work done in an area, we have to make sure the result is safe: this introduces rules and regulations, and the time and monetary costs tag along.

No two people will agree where the balance is, but generally there's regional culture. Hell, Texas allows home-owners to do their own electrical work - does that "drive business away" since some people won't pay for small DIY fixes in TX? I can't say I've ever heard that argued, but I hear it deployed a lot in response to regulations.
