Great to have learnt more about you!

Replicators would be the ideal thing. Apart from the ability to streamline resources and production, it really would render the our current growth at all costs economy as old-fashioned. On the other hand, not that I think of it, possibly not.

As far as I understand particles have mass via the interaction with the scalar Higgs field. Now, why that field is universally non-zero is a different question!
