If you mean by this that you regard firewalls as an aberration,
example of bad design, a totally unworkable solution in the
long run, and something we should ignore when designing real protocols,
then we are in complete agreement.
Unfortunately paranoid organizations have a lot of buying power,
so not all people may be happy with that attitude.
Let's just make sure that if we mention firewalls at all, we
describe them correctly; I prefer to ignore them whenever I can.
