Especially how the entire model will eventually be upheaved by fabricating replicators as a community or personal service, and once one of them get out, well, given a supply of matter and energy, everyone gets one and is their own steady state producer. Genie would be out of the bottle then, and God knows what beyond that.

I think some raw materials are going to be inevitably contested unless we find abundant replacements or reach 100% recycling rate. A replicator won't save us if it needs rare material X.

In theory all you need for an abundance of any element is other elements as stock, a particle accelerator, energy, and time.

In practice, we'd need the price and size of particle accelerators to go way down, the price of energy to go way down, and the time required to go way down before it would make a difference.

Then again... "Anything that is theoretically possible will be achieved in practice, no matter what the technical difficulties are, if it is desired greatly enough." -- Arthur C. Clarke.
