Retail investors have no edge in derivatives, and derivatives certainly don't have the same investment potential as equity (they are zero-sum).
Retail investors absolutely have an edge in derivatives. Look at an option chain. There are maybe half a dozen strikes in both puts and calls. The retail investor's edge is that he gets to choose which one to buy or sell. That may sound silly, but it's more or less an enhanced version of the same edge he has in buying stocks. You place your bet, based on what one presumes is some research and analysis, and the market maker has no choice but to take the other side. You can even sell premium into your bet, which improves your return versus buying the stock. If that's not an edge relative to trading common shares, I don't know what is.
And that's why market makers hedge. But you knew that already. Here's an interesting angle, though. Market makers don't care that the game is zero-sum, because they're constantly hedging against the stock. Even if they lose money on the actual option, they don't care because they make it back on the underlying. Retail investors aren't fighting for their share of a zero-sum pot, they're making individual bets against people who don't care if they lose. Options may be zero-sum, but they're not the whole game.

lol, ok. If you're really that interested my knowledge of options is right up on the level of riskarb's (and I don't use it for trading tiny accounts either).
If you have the options knowledge of a market maker, that knowledge is useless in a small account. What retail investors use to profit from options is a basic knowledge of options and half-decent stock picking skills. Not much more than they use for trading equities, really.
However, transaction costs (spread if you take, adverse selection if you don't, + brokerage/clearing) are higher than the vast majority of stocks, regardless of who your broker is. And no, joining the bid and waiting until you get filled does not reduce transaction costs, market makers (such as myself) aren't stupid.
We already knew you were a market maker, from the snobbery.
Bid/ask spreads are narrower than ever, and as more options go penny-traded the added costs compared to equities will become negligible. Broker commissions are already negligible. The added leverage and time premium (if you write) already makes options more profitable than shares for the retail investor, assuming he was picking the right stocks to begin with.
And the fact that they are zero-sum makes a big difference; equities create nominal wealth quite predictably (given inflation). Options do not, they pass wealth around.
As I've explained above, that's not true. The option market is tied to the equity market, and you're the one providing the link. Thanks to you, there is plenty of money to go around for us retail folk.
