If I wanted to hire someone to survey my house to help me plan a renovation, to get a town permit, I’d need a licensed engineer to make the drawing.
If I was DIYing it, I would absolutely feel comfortable hiring someone unlicensed to get a good-enough drawing.
Making it illegal to get an informal survey of land sounds insane.
It's not illegal to get an informal survey of land. It's illegal to pass a fake one off as legal, which is what is commonly happening with his "drawings".
"Taking a picture of yourself" and "writing your name and address on it" are legal, but if you open a Fake Drivers License business, you should expect to get hassled about it. A tiny line of text reading "this is not a real license and should not be used as one" shouldn't absolve you of all responsibility for your product.
