I don't know, currently they don't make pencils and paper illegal to own unless you have an engineering or architecture degree. And you can even legally use those tools to draw buildings and work out math formulas. You just can't represent the final work as an engineer in specific contexts. The software equivalent would be that you can't sign off on code for a safety critical system without proper credentials. Now that doesn't mean you can't write such code, just like the guy swinging the hammer and striking a nail doesn't need to be an engineer.
