The impedance of the perfect voltage source is supposed
to be zero.

The impedance of a perfect voltage source IS zero.

How close humans can come to achieving such a device
depends largely on the budget.

Bench power supplies come quite close within their
current limits and single quadrant operation.

Spending more money will get you closer.

The fact that 0 can not be achieved does not detract
from their utility to assist understanding.

I, like you, suspect that is a complete
impossibility.

What I would like to see is a TV signal
fed through a source only to emerge unscathed on the
other side and viewable on a TV screen without distortion
just as the theory predicts.

A voltage source has two sides? Explain!
