You would only need an amplifier or transmitter capable of 24 kw PEP to do
that. 6 kw of carrier.
Or you could get rid of one side band and the carrier and only require a
1500 watt amplifier for  one side band.

Lots of people do drugs too. Does that make it ok for everyone to follow?

But what is your point?
