Note I think altcoins can coexist and benefit from pegged side chains (nullifying the risk that pegged side chains could copy and steal value from innovation, i.e. threat of Communism!).
Well, the altcoins stole value from btc innovation in the first place.
No they expanded the ecosystem by increasing innovation (even if in most cases that innovation was only to increase speculation opportunities since many come to this ecosystem for speculation) and that insight is also the generative essence of my insight into what altcoins need to do to survive along with pegged side chains.
If you wanted a monopoly on speculation to drive the Bitcoin price to the moon, then close the doors to entropy (which is only possible within your fleeting Coasian closed system) and attain your miniaturized desktop rendition of the solar system.
Pegged side chains will probably drive consolidation of speculation into fewer variants, because of the importance of capturing the voting power of the peg which is machine verifiably not duplicitous. I think the speculation markets are exhausted/diluted of too many copycoin variants and so this appears to be timely so we can gain synergies.
