"Don't let them use the appropriate/preferred tool for the job and see how much fun it is" is a fairly nonsensical proposal for pretty much every profession.
More seriously, IDEs exist and work, so if people are productive with them, what does "but you'd be less productive if you didn't have your IDE!" gain us? C++ is a bit less verbose, but still the wide majority of devs uses an IDE with it because it does useful things. Programmers of Lisp etc use editors that have tools to edit Lisp files better. etc. I get not liking the existing options as a matter of personal taste, but that's different.
