What laws?  There have been no effective laws enacted.

We've had 20 years of no laws but rather consent standards with no teeth,
and few firewalls installed on a voluntary basis -- and look where we are.

Clearly the time for that experiment has runs its course.

People are trying to use the Internet in production, but in reality the
Internet is just in beta test with organizations playing around seeing how
little they can do (and by "organizations" I mean organizations, not
simply academic organizations).

The new security patches you applied last week -- they weren't on two
weeks ago were they.

So two weeks ago your system wasn't secure was it.

The basic principle of security is defense in depth.  Do not depend on any
one thing because an attacker can defeat it unexpectedly, and be in, and
you won't have any chance of stopping them.
