Earlier quoted context omitted.
The issue here isn't "did delivery apps sometimes impersonate restaurants" (which is why you think this law is redundant), but rather "does this law ban things other than impersonation" (yes, and hence why others are saying a violation of the law need not constitute impersonation).
The point is that the stated reason for the law is impersonation, which is already illegal, but under the guise of cracking down on impersonation of restaurants, the law does much more.
Is it? I don't see anything in the text about impersonation.
