I'll start with some history.
The car was damaged by the PO under the driver side at some point in its past. I just replaced the front rotor that some auto shop guy destroyed trying to cut it. It was thin anyway and he probably should not have attempted it. But now after putting in the new one, my brakes are slightly nipping the very slight rise on the inside of my rim.
I put nice metal master pads on and they are much larger in thickness than the old crap ones that I replaced before, and again the new rotor is about twice as thick as the old worn one.
I also have had a really bad camber in problem on this tire causing me to rotate my tires because the wear on the inside was showing metal.
I pulled my camber in as much as I can. I'm going to the shop next weekend for alignment. The PO put new rims on. Did he need an offset that is only showing up because of the new rotor thickness or is my problem some alignment issue?
2 pictures are the rubbed side and the other side, which has clearance. No rub there but still has the original worn thin rotor.

It looks like the PO put on wheels that shouldn't have been used - and they only fit because the brake pads and rotors were sufficiently worn to allow them to fit. In your situation, if I wanted to stay with those rims, I'd try some thin 1/4" or less spacers to get some clearance between the brakes and rim/s.
It's nothing to do with alignment because there's nothing in an alignment that changes the relative postion of the rim to the brakes - rim and brakes stay in the same relative position to one another and are moved as one unit when alignment settings are changed. I think JCWhitney has some spacers you could use at probably ~$20/pair.

Have you checked your wheel bearing for excessive looseness? It wouldn't cause the wheel to rub the caliper but it could have caused the abnormal tire wear.

A camber problem can also be caused by worn or collapsed upper strut bushings.

Before you spend any money on front end alignment, you need to drop the front struts, and service them (replace struts or inserts if leaking or flat, and replace worn or defective/collapsed upper strut mount/bearing).
