No one who has ever sold an OTM option has survived. Thats how I know OTM options are not overpriced. @nntaleb

Let P = current price, S = Strike price for a put. Let U = price of the put. We're talking about an OTM put, so P>S. If you're selling puts, the greatest amount of money you can lose is S-U. Whereas, if you're selling a call option, your downside is infinite.
S-U is bounded downside. Selling a call option would not be bounded. You have unlimited downside.
