Yes, he wants to, again, tax crypto earnings in the same all other investments are taxes. Maybe you call not getting a special privilege from the government, "anti-crypto", but for me he's just making sure everybody pays the same rate of taxes.
Crypto by its nature in using addresses and hashes is private. The world can see crypto transfer amounts, but nobody can crack your wallet unless you handle it foolishly. Also, without a note in the memo section of the transaction, the purpose of the transfer is private.
If you transact crypto through an exchange that is licensed, you are voluntarily coming out of the privacy laws into the public domain because of the licensing. Just as all investments controlled by the SEC are public, what you privately do with your investment paper is not public, even though you obtained it publicly. But investment paper doesn't have privacy built in with public/private addresses and hashes like crypto does.
What this all means is that crypto can't fall under the same guidelines as other investments. The privacy is built right into it. Since government is there to regulate public, not the private, they need to be careful that they don't overstep their boundaries. To see that this is true, check into Private Member Associations, which, if set up properly, base their operations on over 70 SCOTUS rulings over the decades, that deny government the ability to regulate private operations.

Most taxation on privately done 'income' is prohibited by the constitution... especially IRS taxes. Conversely, contracting with government is allowed just like it is with other people. What the IRS does is to use clever wording in their laws and regulations to make it look like people are required to pay taxes. Then they use clever wording in their forms that make it look like the person who signed up to NOT pay, was tricked into signing up TO pay.
If a person doesn't know how to use straight forward statements to cancel the accidental, contract he made with the IRS, the IRS can only use what their paperwork says, and the person loses in court. After all, the IRS can only go by what the paperwork says. They can't interpret the person's understanding of the paperwork... until the person clarifies it the right way. And people don't generally clarify what they don't know about.
