So any time a piper cub flies it is an emergency?

This is rec.aviation.ifr

So you can fly anywhere you want and atc is supposed to guess where you

He didn't say "anywhere you want".

are going or magically know whom to keep away from your unknown
position? They cancel and stop all flights while you fly wherever you
want?

Neither guessing nor magic is required. Your position is not unknown.
Flights are neither cancelled nor stopped.


Does not sound good to me.

Get your hearing checked.
