Most such prototypes get tossed because of a flaw in the idea, not because they lacked professional software help. If something clicks the prototype can get rebuilt properly. Raising the barriers to entry means significantly fewer things get tried. My 2c.
Not in an industry where prototypes very often get thrown into production because decision makers don't know anything about the value of good tech, security, etc
Should decision makers be more informed? Yes, of course, but that's not an argument for gatekeeping. We shouldn't be gatekeeping software or the web. Not through licensure or some arbitrary meaning of "effort". That will do nothing but stifle job growth and I'd very much like to keep developers employed.
