Yes, you should try to write quality code.

Yet almost everyone fails.

You should also try to write quality laws. But when you fail, do you want the same sort of consequences as with code? How much time, effort, and money has been lost to hacks taking advantage of errors in code?

I would love an interpreter/compiler/processor that knew that I didn't intend to allow a security vulnerability so anyone could escalate their privileges. Sounds great, truly.
