The bottom line is that they want cryptos to simply go away. The IRS (U.S. Government) doesn't like cryptos. The crooks at the banks don't like cryptos. The politicians that accept political donations from these same banks don't like cryptos. They are well aware that it will be nearly impossible for miners to keep up with the daily exchange rate of every single coin we mine. With the threat of fines/penalties/prison time for not keeping up with all this paperwork, they are hoping that people will simply give up.
It's actually a pretty smart plan. The public sees the government as embracing cryptos. After all, they are telling us we can have our cryptos so long as the government gets it's fair share. Seems pretty rational doesn't it? However, the public has no idea the paperwork that would be required to actually fulfill that obligation. The IRS is fully aware of this.
