No, that was being done long before this ruling.
Roberts called them out by rightly labelling it a tax.
A label. Yeah, that'll show 'em who's boss. I bet they are quaking in their slippers.
No, Roberts rubber-stamped what was improper if it was a tax—as it originated in the Senate. He allowed them to go ahead with it by relabeling it as a tax even though they had positioned it otherwise.
The net effect of his ruling is that Congress can micromanage everything just like an expanded commerce clause—as long as they do it technically by the coercion of taxes rather than the fig leaf of the commerce clause.
This is a hugely bad deal for the country.
