Translate the following abstract into formal French: "The 2020's brought renewed interest in monetary diversification, and especially in the anchoring of money supply and worth to primary commodities. This is not new: From around 7,500 BCE in the Fertile Crescent standardized clay tokens represented units of basic goods and services, and from 54 BCE China's Han Dynasty maintained a "constant normal granary" at pre-published stable prices. From the 1920s through the 1960s many prominent Western economists proposed commodity reserve monetary designs, but these were opposed as price-distorting, complicated, manipulable, and lacking real stability. The Earth Reserve Assurance (ERA) framework resolves distortions and complications of earlier commodity-anchored designs by shifting the reserve concept back one stage in the value chain, so that Earth itself is the "warehouse". The natural productive capacity of Earth's functional ecosystems underlies our ability to obtain primary commodities, factors such as: the quantity and quality of topsoil, fresh water, metal, minerals, and energy deposits, species populations, diversity and integrity, land and water habitats, regional and global biogeochemical cycles, and other "ecological infrastructure" types. Deployable through existing currencies, ERA offers an incremental path to sound money in complementary physical and electronic modes, while meeting all four of NAME_1' functional criteria for sound money."
