But you can port any and all features to sidechains or Enigma [1], and in doing so make them accessible to a much bigger market, denominated in BTC which is a more stable and proven unit of account.

Or at least that's how the story is supposed to go. In theory, porting nice-to-have features to a larger audience results in more revenue and more overall societal benefit than starting a new scarcity race, which Ethereum has done, pitting investors against each other.
