Don't forget selective enforcement, which is probably the biggest frustration and source of uncertainty and cost. Not knowing if doing one thing one day will be fine the next day are not conditions most businesses thrive in.
There isn't enough manpower to fine everyone doing anything wrong every day. Parking fines are generally much higher than the parking cost because it's impractical to catch every illegally parked vehicle every time; the whole idea is to make the expected cost of parking illegally greater than the expected cost of parking legally, while limiting the cost of enforcement. Similarly, I am under no delusion that speeding is fine on days I don't get caught.
I'm ok with regulation pertaining to food standards and service.
I'm equally ok with Apple's App Store curation.
But it's a tricky line to get right. When visiting countries with street food cultures, you can generally do ok by following the local crowd. But that's because the local establishment isn't going to screw the pooch and poison the regular clientele if they can help it.
We live in a society attempting to outsource trust, whether by government regulation, flimsy technological crowdsourced reputation or other equally ephemeral measures of quality.
You should look at the law and decide if you can operate within its confines. Counting on it not being enforced is not really a sound business strategy.
Don't park next to a school or food market? You can avoid that every day. I think that is a smoke screen for the real problem: a terrible business case.
