There are generally no laws in the USA against creating and using alternative currencies. I can buy and sell using Euros or Monopoly money or whatever if I can find a willing counterparty. However, if those transactions are taxable then I have to report them at the US Dollar fair market value equivalent and pay any taxes due in US Dollars. And if someone owes me a debt I am required to accept US Dollars for settlement.

This is not correct. If you try minting coins, you can be shut down. You can buy and sell using whatever you want, yes. There aren't laws against using alternative currencies. But there very much are laws against creating them.

No one uses coins for anything important. There are no laws against creating your own alternative paper or electronic currencies.
