Places / real economies like Greece ( although Estonia would also be an interesting place as its government already invested in blockchain database solutions )
could imho benefit from a state guaranteed Cosmolocalization Scrip
For example, a government could decide to issue Scrip ( the state of California did issue IOU's, a few years back, that could be used to pay taxes )
and decide to spend it into existence in sectors of the local economy it could even decide to define and update ( using scripp in the form of a token / smart contract ),
ideally to generate access to currency in parts of the economy that are under served in currency, and especially to enable services and production that can reduce dependency on imports and/or bootstrap sectors that could also lead to exports.
It could also track usage of the scrip through analytics enabled by its tokens on its blockchain ( or holochain ? ) , understanding the effects and usage of the scrip. ( potentially anonymized ? )
This would fit perfectly within a Cosmolocalization narrative.
Such a Scrip could also function so as to reduce paper work ( online accounts, digital payments ) and be adapted, not to replace Euros, but as a complementary currency. For example, imported goods might only have a percentage of the price of the good related to local services in cosmo scrip.
The government(s) could also generate demand for the scrip by accepting it as a medium of tax payment. Although to avoid it replacing all euro tax income, the government(s - including regional or local ) could for example accept only a certain percentage of a persons or company's scrip as tax payment. Similarly to a dual complementary currency mode used for other goods.
It could experiment at first with anything that is locally produced, and also start by allocating an addition to the current euro salary of government workers, in scrip.
If successful, it could also enable loans in scrip, by local businesses that can use it to develop local production ( and ultimately reduce the need for imports ),
and it can also strategically enable clusters of interdependent businesses that can benefit from each others services,
and can also ultimately facilitate online markets and a c3 ( commercial credit circuit )
