I think the point is that all cryptocurrencies that we have currently are experimental in that sense, and so it's a good time to experiment with unproven concepts. Maybe that means ETH will crash and burn, but so what? It's a minuscule part of overall economy, so aside from people who decided to seriously invest into it (i.e. alpha testers), it's not a big deal. But, on the other hand, we do want to figure out what works before we start using these things at scale, when it's much harder to change.
