Upon close examination, the answer is clearly yes: The American Revolution was caused in part by the British monarchy’s efforts to eliminate firearms commerce in America.

(Whether abortion rights should exist at all is a separate question; under Roe v. Wade and its successor cases, the rights of abortion providers are plainly recognized.) It is true that such businesses can assert third-party rights on behalf of their customers, but the more fundamental point is that the businesses have constitutional rights of their own.
