and, of course, there are so many criminals in the world that we might
as well give up and disband all police forces because that horse has
bolted too. and CO2 levels are so high now that it's pointless trying to
even ameliorate the inevitable harm. and so on.

i think you'll find that my point was the opposite of what you're saying
flash, java, etc by default - is an essential part of the solution.
software that requires users to make a positive choice "yes, i want
to run the executable content on this particular site" rather than a
negative choice "no, i don't want to run stuff from that particular
site". off by default, enabled by the user when they perceive a need.
users may be no better at making such positive choices than they are at
making the negative ones but:
- they'll be safe BY DEFAULT
- they'll have to think about the issue every time they decide to
enable executable content for a site.
- they'll get better at it gradually with practice
- web-distributed malware will have a MUCH smaller impact because it
will only directly affect those who make a deliberate choice to run
code from an infected site.
- incidentally removing some of the incentive for writing such malware.
and the price for this is that web designers will have to actually THINK
about what they're doing and not get carried away with their usual
thoughtless technophiliac fetishism ("ooh, shiny! pretty! it must be good")
small price to pay, IMO.

not saying "it's impossible, people are irredeemably ignorant so let's
give up" would be a good start.
