You would because I did. I started coding CGI scripts in C in 1994 then discovered Perl's CGI.pm

Then I handcoded SQL queries and discovered marshalling / unmarshalling / SQL injections etc. Then started using some library to spare me the issues.

Repeat for any piece of the stack.

Am I going back to frameworkless? No, because I would end up without customers. "No sir, it takes 6 months, not one, because I have to hand code everything or use my own buggy library instead of X which a zillion other developers use."
