My point of raising the topic of techum, and of the example before it,
Tefillas haDerech, was to suggest just the opposite!

How can a modern situation serve as a "sanity check" of a din made before
that situation was remotely possible, never mind commonplace?

I was suggesting that today's reality can have norms Chazal didn't write
their din for. And therefore the fact that a mitzvah now has little
applicability may NOT mean we're misunderstanding the limits Chazal set
to it.

When Chazal made the reduced measure for techum, there was nothing
similar to today's metropolis, never mind a chain of them in one big
Megalopolis like Boston-Washington.

Tir'u baTov!
