Seen house building regulations recently? Most countries will let the home owner do things they'd never let a contractor do without a permit. There's a lot of different laws for home or very small scale selling of various goods, brewing, canning, single person doing business as companies, etc.

> home owner

But in this analogy, we aren’t talking about a person doing coding at home only for their own use, are we? Isn’t this about small companies - I.e. whether there should be different applicable laws if you hire a small construction company vs a large one to rewire your kitchen, etc?
