In your statements, you never specify what a "large conductor" is.
Today, transmitters are often very small and still they work OK without
any earth connection.
How large should a "large conductor" be?

Probably it is the coax: "Many conventional coaxial cables use braided
copper wire forming the shield".

The transmitted signal flows only along the inside of the shield of the
coax. The outside is supposed to carry no signal. If it does, there is
a problem with the antenna system.

I also belive in each Tesla's word. He discovered that in his secondary coil
is the oscillatory electron flow from the earth into the air.
Why is it impossible?

We do not operate our transmitters in the region where electrons start
flowing into the air, because we do not like arcing. Tesla did, but he
was in a different business.
