Speculation is enabling to non-coercive frameworks. If I say a token has a use value that I will use to supply goods and services, you may want to acquire that token. If I can also control issuance and supply of that token, then, short of direct threats of violence or enslavement, you must negotiate with me or with a marketplace.
Most of the ill in the world has something to do with gatekeeping replacing speculative activity.
