Of course you _can_ build great and secure systems without any frameworks. But do you _want_ to do that? If I had to build everything from scratch for which I'm using a framework or library right now then I would need _significantly_ longer which would place me and my team at a clear disadvantage against the competition.
There are tradeoffs for sure but you can't have everything all at once.
