Well, surely there are Ones - psychopaths - who lust for power over Others, and money provides the tool to widespread power.  And yes, technology is required to obsolete that tool.

The foundational function of money - in any form - is to account for the energy We each add into a system.  This gives Us proof that We added that energy.  In scarcity environments, where all hands are needed to get needed things done, this made sense.  Don't want "skaters" taking but giving nothing.

In the rare societies that emerged in abundance - "island paradises" mostly - no accounting for the energy Each added arose.  Though They had varying social constructs - religious mostly, or ideological - there was no "money" used.  No need to prove One added energy with goods and services, or anything representational of that - shells, beads, metals, paper, electronic bits.

Of course, We are long post-scarcity (no political baggage with that), but the moneyed psychopaths in control on Our planet (by virtue of money) do all They can to maintain the moneyed setup.

And given the foundational function of "money," it is clear that free energy tech would obsolete the point of "money."  So...  They avidly hide and suppress all such technologies.

Given My father worked on such a technology - it went into black projects in 1959 when I was 2 1/2 - I know We have such tech.

So...  My work is to motivate Those with the wherewithal to get free energy tech out in the open - without patents to alert Them.

Once money is obsoleted, no One will have widespread power.  And Ethics - the three Laws - will stand.
