Even with $250k batting at 0.5R, 2 trades per week only nets you $2500 per week on average if you risk 1% per trade, ok it's more than the average worker makes but that's a fairly low professional salary.
LK, to be fair, that "only" is like 50% return on capital over the year. Who wouldn't be happy with that? Anyway, I think your point was on traders being undercapitalized and prone to volatility drag. That I agree with - and I think that traders who don't believe in it are fooling themselves.
