The real reason for having to account for all selling that totals more than $600? Push people out of the gig economy and into wageslaving for the corporations.

The IRS is telling people to be ready to report any activity, like ebay sales, in which they've received more than $600 over the course of the year. This is clearly meant to target the gig economy like small-time resellers. Are they doing this in order to attack the gig economy and make sure people are working at corporations?
