The regulation of interstate absolutely gives the Federal government the ability to agbrogate or invalidate state law. If it didn't there would not be any reason to have it. Although the Federal government actually owns far more land than just D.C. most commerce does not happen there.

If it didn't give the federal government this power then every state would just pass a "nuh uh!" law every time the federal added a tax or whatever to stuff.
