I respectfully object to most of your statements.
The first and biggest is that you (and I) can only speak for ourselves. One online golfer, one voice. Thus, one golfer (you) wants to hit it left-handed. Only one supporter in this thread I fear. Get more supporters, then you'll have more voices :)
There certainly are non-golfers here, alas we don't know the number.
Alas, from a quick search I know that from 10-20 % lefthanders in the (golfing) world, only a small number play lefthanded. Numbers are at about 2-5 % of all golfers.
So the potential may be 1-3 % for a left-handed avatar, which - I repeat - costs WGT a lot, but for which revenue? Ev1 arranges with a right-handed avatar, including you(?)
