10,000 plus funds-- 5 trillion of assets with more coming everyday creates quite a universe from which to choose....
Well, reasonable estimates of the hedge fund industry put the size at somewhere between 1.6 and 2.5 trillion.

In addition to the above, the largest funds (e.g. $5 billion or more) are going to account for a substantial portion of that.
Then on top of that, you said your guy refuses to pay management fees, which cuts out an even bigger chunk of successful managers. (If a manager can successfully raise on his own terms, why is he going to waive fees for some guy who is practically guaranteed to redeem at the drop of a hat?)
Same goes for lock-ups too. You can find funds without lock-ups, but the more restrictions you put in place, the more high quality managers you exclude.
And then on top of THAT, while hedge fund strategies may differ, a huge majority of them are heavily correlated. You've got a truckload of value guys, a truckload of merger arb guys, a truckload of distressed debt guys, and so on. There is just not that much differentiation at the margins in a lot of these spaces. And the mention of being too quick to cut a strategy is right too -- sometimes an entire strategy space (value, merger arb etc) is running hot or cold. It doesn't make sense to cut it for that reason and miss the return to form.
And finally, last but not least, the long tail of the industry includes thousands of tiny little funds with the lifespan of mayflies - guys who are trying to take their shot, not quite making it, and closing their doors in a year or two. This portion of the industry is in constant turnover.
Put it all together, and I would guesstimate the total asset amount available for your guy's "no management fee, trade 'em like stocks" strategy isn't even 10% of $5 trillion, maybe more like 5%.
But I agree on the gambling thing anyway, at least from this guy's perspective. The way you describe it, he sounds like a bored sheik fucking around with racehorses, as opposed to someone actually trying to make money. I'm not really sure what's professional about that at all.
