After the revolution it is important that the standards of living do not plummet, so money should not be totally abolished [Aufheben] right away but it should instead coexist with a labor voucher system that would replace it gradually. In addition, there should be a third kind of currency called "gems" [Juwel] given for work that is determined critical and can be used to buy the most limited luxuries.
In order to stop money from turning into capital, the revolutionary government should sell "boxes" whose content is unknown to the purchaser but that have a low chance of containing extremely desirable items unique to these boxes. There should also be a "pass" system that workers could purchase for each year, that rewards them with different kinds of items including the currencies for every x hours worked. If you got enough levels in one year's pass, it could even give you enough currencies to buy the pass next year.
