observations:

1. The model is over-simplified, in reality it's unlikely that BLUE
would consistently achieve 80%.  However in reality it's also
unlikely that RED would enjoy a linear relationship between
obfuscation and success, specifically, the more RED obfuscates the
less success it has.  Both teams might suffer diminishing returns
from their efforts. (for the purposes of the above model, these
effects have been allowed to cancel each other out)

2. The model has a constant 1% reduction in the victim rate, this is
debatable, however it will never go upwards, eg., there is nothing
RED can do to push that number back towards 100%.  Conversely,
everything BLUE does pushes that number towards 0%.  In addition,
other anti-phishing technologies will also be pushing the number
towards 0%.  GREEN itself might even push the number down.


FLAWS:
1)  This also assumes that no new users ever start using the Internet that
may become new victims
2) It also assumes that all evolutions in phisher techniques are
predictable.  Anyone following the industry knows that all sorts of things
have been done so that their phishes seem more realistic/plausible.  And,
after using these new techniques, RED can push the number of victims back up
-- in direct contradiction of your statements, which do not reflect what
happens.

These 2 facts alone explain why phishing isn't the simple fix you have made
it out to be.  Your model is flawed, as it is based on flawed assumptions.

not interesting anymore.
