I have a row of sunchokes that has branches interlocking, and was wondering if they will overcrowd, or not. I can water them every day, and found this article (done half an hour north from my house) that says I can do two crops in my area in a year, and produce a lot more than doing a single picking.

Is 2' spacing ok even if the branches are touching?

Give them at least 18" of space between crowns and you will be fine. It's root crowding that can harm yields, not really top growth crowding. If the stems grow close enough to touch adjacent plants it's a good thing, as it protects the soil.

I don't know about 2 crops in a year. In my area they take too long to mature. While you may end up with somewhat more yield/area in a year, you are also using twice as many starts. You could give it a shot.
