he answer is always "Yes," but they probably won't. The Commerce Clause is one of the most over-extended provisions of the Constitution. Just about everything qualifies as interstate commerce. I can see them overturning a few egregious rulings, but the general framework will always be the same. There was this
one ruling where they said growing weed for personal use falls "squarely within Congress' commerce power because production of the commodity meant for home consumption, be it wheat or marijuana, has a substantial effect on supply and demand in the national market for that commodity." In other words, if you can produce something by yourself, for yourself, it affects interstate commerce because it means you don't have to buy it. IMO that is absolute bullshit.
