That's another huge difference between software engineering/web development/coding and something like medicine; there are few parts of the latter where screwing up won't have major consequences, and many parts of the former which won't.
In that sense, I guess you could say tech is less like a 'field' or 'industry' and more like part of life that a bunch of different fields or industries depend on. It's like how 'writing English' covers lawyers writing documents for use in court, teachers teaching students in schools and colleges, authors writing novels and businesses writing copy for their websites/brochures.
The former two cases would have some sort of licensing because they have actual consequences if someone doesn't know what they're doing, whereas the latter clearly wouldn't.
Meanwhile if your average developer or software engineer screws up, it's usually not a big deal. It might be in a few specific instances (like if they're working with medical software or systems onboard planes), but in most cases it's just 'some small business' website goes down' or 'a video game crashes'.
