I would advise you need to start considering the physical energy effects of all money use in all scenarios, to know what will be the future of money.
Its about to become a very hot topic, the ethics and honesty of separating money from energy considerations, the latter being the more important consideration which has to take precedence in concerns for the physical environment.
Money has to be brought into line with energy to make it honest, so as to obtain a physically sustainable world.
This runs so deep it has to affect law and order, causing law to be rewritten where necessary to be restated in terms of energy rather than in terms of money as it existed in the "Old system" of profit.
This has to be sorted out to ensure the physical future of the planet, because it's becoming increasingly obvious that the temperature rise and planetary destruction are directly related to business for profit.
In fact we can numerically trace all profit made in history to planetary temperature rise, and this stacks up perfectly with the theory of thermodynamics, again numerically to show that the temperature rise is reversible with appropriate use of money-as-energy.
You should be prepared for profit being identified as a dishonest, planet destroying energy con, because this is what it actually is, physically, since money is physically energy, always, the energy property of money is what has to be honored, to conform with the energy laws of nature, since the base currency of nature is energy, we have to align our money with that, to avoid falling out of step with nature.
Again the degree to which we've fallen out of step with nature is indicated by the temperature rise.
Until we recognise this and act on it, we are trying to live as a species in an unsustainable dream world which does not reflect the physical reality of nature, and the time we remain out of step like this is proportional to, and indicated by planetary temperature rise, which is already in the red line of flashpoint.
If all of this seems like gobbledy-gook to you, alarm bells should be ringing because this is the hard physical reality that absolutely will be enforced by nature, we either go with it or burn, literally.
