We should all be able to use cryptocurrency within the open, free market.
It is my opiniom that cryptocurrency should never be used as a form of currency issued by the federal government of the United States of America as a standard because it is unconstitutional.

To coin Money, regulate the Value thereof, and of foreign Coin, and fix the Standard of Weights and Measures
Just to be clear, at no time has anyone ever even hinted the government will be issuing cryptocurrency. That's not even possible. The Fed wants to issue a CBDC. A Central Bank Digital Currency is not a cryptocurrency. Don't get the 2 confused.
Cryptocurrencies rely on proof of work and public blockchains. Bitcoin is an example. A government agency can not "issue" or "coin" something like this. It is impossible. It can only be mined.
There are also degraded blockchain currencies like Ethereum that now use Proof of Stake. They don't qualify as crypto since they can be fully controlled by an individual/consortium, and are more like corporate stock or securities.
Finally, there is Ripple and CBDCs (what all the governments are pushing for) use permissioned authenticators, and are not decentralized in any meaningful way at all.
The government can issue a "cryptocurrency" but likely it won't be permissionless. (Permissionless chains, like Bitcoin, can be mined by anyone without permission of a central authority). Instead they will create a cryptocurrency that is "mined" be a central authority, or by "miners" who must be authorized by a central authority. That is, a permissioned chain. They might call it a cryptocurrency but they will never push something that they can't control. After all, otherwise they could just stop cracking down on Bitcoin, since chains already exist that they can't control.
If the miner must be "permissioned", then it is not a public blockchain and therefore not a cryptocurrency. You have just defined a CBDC, which is essentially what Ripple is.
