Decentralized control of cryptocurrencies.

The existing monetary financial system of the USA has strict control allowing to regulate the issue and creates rules for centralized financial regulation. One way or another, all countries of the world build their financial policies on the same principle, focusing on the $ USD exchange rate because the world does not yet know another better system. With the advent of BTC and other crypto currencies, there was a similar issue of control, but there was a problem, how and who will exercise control? All the developers, focusing on the dollar in various ways and options, decided to invent a square wheel (cryptocurrency Fiat) in the end, a dollar called centralized stablecoins USDC, USDT and BUSD and supposedly decentralized stablecoins (UST, DAI, FRAX, FEI, OHM) turned out again. The example of LUNA showed the inconsistency of such ideas. An attempt to link centralized finances with decentralized ones leads to what Satoshi Nakomota refused by inventing BTC. Satoshi's idea is to create decentralized finance, which should and will exist in parallel and complement each other by transforming.

What do you think? Is it necessary or possible to control a decentralized cryptocurrency or not.
