The same problem exists in non-networked investment vehicles. Clever people can create derivatives and convince less-clever people to buy them, not realizing that the math actually simplifies out to "heads, I win: tails, you lose". The capital markets industry has never been able to keep clever people from making a little more money for themselves at the expense of a lot of money that would otherwise have gone to investors. At least with ETH and its future competitors, the specific sort of cleverness that is required to profit is very close to the cleverness that I now possess. Not saying I'd put a dollar that I can pay actual bills with into ETH right now, just that it seems more approachable to me than traditional investment, barring only the low-fee index funds. But those are plenty good enough for me right now, as I tend to shy away from games of skill where merely good players are routinely slaughtered by expert hustlers.
