I think services like Strike could help to some degree. Strike allows you to make payments directly from fiat to sats. People that want to send/receive sats can do so, and people that would rather deal in dollars/fiat can do so. It does introduce some kyc into the payments side of things, but only for those users who choose to use those services. Solutions like that would at least give more non-bitcoiners the option of participating economically in the network.
