Agree!

I don't think there's an either/or here.  Yes, if you *can* change the
tools/libraries/development environments to prevent attacks, or reduce
their effectiveness, you *should*.

That said, a fool with a tool is still a fool.  There's no way to create
a development environment that can't be misused.  Thus, you'll always need
to educate and train developers for situations the system cannot prevent.
In the long term I think this will be easier, because novice developers will be able
to learn from the many experts around them.  Today, the number of
developers who understand security issues is a vanishingly small percentage
of the total, so the novice has no one to learn from.
