It could well be that in a future phase, human society will not be so focused on the importance of "money", which for a large (but not total) percentage of the world population has been set up as a turnstile for access to necessities, real and perceived, and then to "luxuries". Younger people (under-60s lol) who have lived all their lives in a relatively stable single currency environment, especially in the US may be having a hard time realizing that money goes through change just like everything else in collective and individual life. Uncertainty is baked into the monetary "cake", whether we go back to Babylonian clay tablets, to the receipts issued by the Knights Templar or the Venetian bankers and now up to present times. Before computers, since the 19th century, funds have been "wired" via the telegraph network with analog reconciliation along the various "nodes". Are "cryptos" any less ephemeral, or subject to manipulation than fiat currencies that are themselves almost fully digitalized? I think this is a moot point.
Exchange works because of trust, and falters when trust breaks down, as has happened time and again in history. A significant part of the population is already in a phase where multiple forms of "money" are used, with a return of interest in topics like the different functions of "money" often distinguished as: medium of exchange, storing wealth, measure of value, standard for deferred payment.
Let’s put in a good word for the burgeoning community working to advance the society intellectually and spiritually, especially online. There will always be a place the printed book and specialized magazines; and whether these are sold online or in shops, digitalized processes are required for printing, shipping, royalties and the payments at these various stages. While cash can and should be used for local purchases, sending it through the mail has too many drawbacks. In times of turbulence, which will pass, we might all think of adding to our list of "must do" how to ensure the continued support to our favourite websites and authors.
