If crypto vanished tomorrow, would onchain platforms still have a future?

Genuine question I've been thinking about while building Sphinx, an onchain commodities platform.

Take away the tokens and speculation. The actual tech is still useful. You still get 24/7 markets, instant settlement, transparent liquidations, and no middlemen eating your margin. None of that breaks if any token goes to zero.

A platform doing perps on oil, gas or wheat feels way closer to a modern version of the CME than a standard DeFi casino. Calling it crypto almost feels wrong.

Curious what you think. Does onchain infrastructure actually have enough value to survive without the speculation? Or is the liquidity just too dependent on crypto money to ever work independently?
