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.
