Couldn't agree more. I would add that the many cryptocurrencies that have been created since Bitcoin (Litecoin, Dogecoin, Peercoin, etc.) are evidence of widespread unmet demand for sidechains, which fulfill the need for cryptocurrencies that:

* have global mining infrastructure, liquidity, and network effects comparable to Bitcoin; and

* allow for fail-fast, iterative, distributed experimentation, which is necessary for rapid innovation.

A lot of people want this!
