By your reasoning, since tons of C programs can't use strcpy() correctly and thus contain buffer overflows, it takes a C master to use strcpy() correctly. I'd say instead that the kind of reasoning is wrong and that even experts can make beginner-level mistakes (not so often). But these are the kind of mistakes a good framework/language/etc. should try to prevent - especially if security-related. Tons of research tries to reduce error-prone programming activities.
