The purpose of this seems to be to spread wealth to the "laborers" by incentivizing those with money available to save into consuming more than they otherwise would. The laborers need to have access to fulfilling, goal-oriented jobs. That is the solution to that problem, not a currency noone has any incentive use that encourages people to consume and pollute.
You have to look at and understand all aspects of a currency before deciding on what you think will happen. Investment has always been the tool that takes underutilized wealth and puts it to use. Whether or not it is put to
good use may strongly depend on how the currency functions. Investors in a demurrage currency will look for long-term, renewable investing rather than short-term, resource dwindling gains. When gains are likely to be realized, investors will have to be very conscious about what to do with those gains and must realize that overproduction is only going to lead to a larger loss due to demurrage if more investment cannot be quickly found. So rather than promoting overproduction (and therefore overconsumption), investors are forced to stop and think about the diminishing returns that comes with a currency that has demurrage, or they will quickly find themselves penniless.
But yes, no one is going to use a currency with demurrage when there are alternatives, imo.
People make better decisions after considering things from a number of different perspectives.
Even if this were true (it is a
hasty generalization), the expected outcome on encouraging a high time preference is that either: 1) investment dwindles and there are very few "goal-oriented jobs" and people without money suffer (though this may be somewhat specific to bitcoin and the lack for need of a banking system); or 2) consumption rates will eventually equalize and it will just be older people that consume more now that money will have no meaning sooner rather than later.
If the value of money stayed relatively stable with some inherent risk of loss due to investment (a problem "avoided" by things like the FDIC), investing/saving/consuming could potentially equalize much quicker to something of a steady state. Overproduction/over-investment would be much riskier without governments/banks being able to print money.
Many of the problems attributed to fiat currencies that bitcoin supposedly solves are really just problems of government mismanagement, and not something that bitcoin inherently solves. Over-investment leads to over-production/consumption, but this is encouraged by inflating currency and government controls. Do you really think that a deflating currency is going to support a steady state, or will it support under-investment and under-production? Why utilize money to produce when the act of doing so will likely devalue it (more in circulation) and there is risk, when merely holding the currency provides a near-guaranteed return? Investors are going to have
quite the pickle.
