It would be interesting to base money on something objective. Like say, the energy release in the ATP-->ADP + P reaction. See, if that reaction fails, then you die. So it has real value in easily understood terms.

We could base the dollar on say, the energy released by a mole of ATP which happens to be about 30 joules. Knowling that, we can relate money in proportion to a fundamental process of life. Conveniently, we can also relate it to things like oh, hydrocarbon value, which has a latent energy associated with each type of molecule.

By knowing these things we could then tell exactly what things should cost, in constant, universally understood terms.
