comagnum,
I think it is too much of a blanket statement that nearly all retail options traders (e.g. folks like me) lose money and lose big (4.5% of capital per month or 54% a year according to your article).
If you mechanically sell covered calls, CBOE's own back tests indicated your return would be comparable to buy and hold but with a much better risk adjusted profile. If you sell cash secured puts, your return would be better than buy and hold:

What about retail doing our own buy-write and put-write?
I did that when I started trading options in 2013, mechanically selling monthly covered calls and puts. I did hundreds of trades in a six months period. Net result: I did a little worst than buy and hold, mainly because of commission and bid/ask slippages. Of course it is only one data point.
If a new options trader starts by selling covered calls and be conservative, find the right conditions to enter the trade, he/she may not make a lot of money but likely would not be losing 4.5% a month.
We should warn new traders that it is not a risk free proposition and get rich quick scheme but telling them they are nearly guaranteed to lose money is maybe too harsh.
