Abe - 

That’s correct - but that does not require having static addresses to accomplish (as you postulated earlier), 
rather it just requires having appropriately functioning logging apparatus.

Yes, it is quite obvious that a degree of care is necessary.

As with all enforcement, it is a question on changing to breakeven point calculation on incentives & risks
for the would be perpetrators, and presently there’s almost nearly no risk involved.

Overall, this environment is favored by multi-national businesses with perpetrators riding along in the background. When security is breached, there are more than enough excuses to point the finger to. No wonder the outcome has always been disappointing for the general public.

Indeed.

The starting point is to review the root differences between the Internet and the traditional communication systems. With near half a century of the Internet experience, we should be ready to study each issue from its source, not by perpetuating its misleading manifestations.

That’s one possible approach, although before becoming too enamored with it, it is probably worth remembering] 
that the “traditional communication systems” have also suffered from similar exploits occasion (they’ve been fewer
in number, but then again, the number of connected devices was also several orders of magnitude smaller.)
