I thought we were talking about the DAO failure, ETH and ETC.
I neither trust or don't trust the profit motive.
Well, without a profit motive, and only with (so-called) generous, (so-said) altruistic, collaborative people, the block chain concept wouldn't work, and would be totally exposed to one rotten apple.
But the profit motive has to induce sufficient antagonism, or it won't work either. What we saw with ETH was that there was a profit motive all right (that would in principle make it work) but there was too much collusion and collaboration between the entities, which made the fork possible. Too many greedy people with important roles (say, devs) had a common goal: getting bailed out. They all looked in the same direction, even though they were greedy. That was the reason for the failure of the block chain immutability.
That said, the thing resolved in an amazing way: those that colluded, have now their own, bailed out, block chain, and the very small minority of non-colluders have their own, original copy running.
It is what it is. So far, it is ensuring that ETH will survive and ETC will be relegated to the DOGE class.
Well, I think it doesn't really matter: the dream of ethereum is dead in any case. There won't, for a very very long time, be complex monsters like the DAO running on ETH and/or ETC. Little Ponzi games like this one:

https://forum.ethereum.org/discussion/6439/etheramid-multi-level-social-invitation-game-no-ponziand, who knows, maybe smart bicycle locks are now the realistic ambitions of ETH and or ETC.
And yes, you can use ETH, because for small game, there won't be bail out forks and the chain will be reliable too.
Your belief in the power of the profit motive to align incentive structures and your belief in the superiority of ETC over ETH are contradictory.
No, ETH failed to solve the Byzantine Generals problem because of too much collusion of interests. ETC has succeeded in keeping this solution, even though only a minority of former ETH users think so. It is a bet of which the outcome is uncertain, but I'd think that the ETC people are potentially in a better position than the ETH people.
After all, most of the value of ETH came from the dream of megalo smart contracts. A significant part of ETH was locked up in the DAO, which was the "engine" of the value rise. The DAO holders were of course the first line winners of the dream, but the whole ETH holders went up with it. But given that the DAO is dead, and probably most dreams of DAO like projects which were the driving force behind the ETH value, are dead now, rationally, the ETH must be strongly over valued. So the ETC price may be much, much more in line with the value of a tiny smart contract ponzi game platform than the market cap of ETH, which has no much growth space any more.
That said, ETH is of course also a simple crypto currency, and there's no reason why ETH wouldn't thrive as a crypto currency. Maybe institutional investors in normal crypto even find a value in the bail out precedent of ETH, and consider that Vitalik and the ETH people are reasonable people one can talk to if one has difficulties, and they will find a solution for you.
So in my opinion, ETH is, after the fall of the DAO, and all DAO-like dreams, now strongly over valued, but on the other hand, a bail-out crypto currency is maybe something institutional investors may find attractive. In other words, what was lacking in crypto land was a rewindable block chain for important people, and there might very well be a huge institutional demand for that. ETH has all its reasons of existence there, being the first such currency having shown that block chains don't have to be immutable, and transactions don't have to be irreversible - at least for important people, not for small players. I'm sure that that proposition has a big market: a crypto that can bail out important people, but that keeps the small people play by the rules.
