I simply asked which of the two options you were proposing we should
use, and why you think the problems that have already been discussed and
agreed upon dont apply in your instance.  Other than because youre going
to write a perfect router that does magical

Ive taken a lot of the points onboard, infact, if you bother to read
back through the thread, youll find that I address almost every single
point individually.  A look back through the thread shows 37 emails, and
you joined the thread at number 31.  You'll also find that not only did
I take onboard the points, but we even worked out solutions to make
routers be able to route properly through these areas.  Im guessing
since you posted to the thread a week after it happened, that you must
have missed bits of it, and are using personal insults to make up for
your inability to read.

You suggested that "If there are obstructions, then they should be
mapped to make OSM more accurate..".  You obviously missed the whole
concept that routing around objects is easy when you know whats there,
the problem is, what do you do when its not mapped?  What if someone
only maps the area from aerial imagery and doesnt tag anything else?
What assumptions do you make, that the area is traversable?
