It’s not obtuse regulation, it’s explicitly by design. In most places in the US, you cannot operate a business in a residential area that serves the public. Businesses that do not serve the public (like a tech startup or someone working from home) are fine. Ice cream trucks are also not allowed unless you have a proper business license / permit.

A mile on a bike should take about 5 minutes too.

If you have dated exclusively Asian women, but profess to feel attraction to other races, then it’s de facto yellow fever.

If you have a business like a law firm where it is VERY IMPORTANT that a PDF has certain qualities, free tools for PDF creation can be a big gamble, especially if you have to open a PDF that someone else has created and do changes to it. And the cost is pretty trivial compared to the cost of messing up.
