firms] from undertaking competitive pricing” or “deprive[d] businesses and consumers in other States of ‘whatever competitive advantages they may possess.’ ” Healy, 491 U. S., at 338–339 (quoting Brown-Forman, 476 U. S., at 580).
In recognizing this much, we say nothing new. This Court has already described “[t]he rule that was applied in Baldwin and Healy” as addressing “price control or price affirmation statutes” that tied “the price of … in-state products to out-of-state prices.” Pharmaceutical Research and Mfrs. of America v. Walsh, 538 U. S. 644, 669 (2003) (internal quotation marks omitted). Many lower courts have read these decisions in exactly the same way. See, e.g., 6 F. 4th, at 1028–1029; Association for Accessible Medicines v. Frosh, 887 F. 3d 664, 669 (CA4 2018); Energy and Environment Legal Inst. v.

Add to the extraterritorial-effects list all manner of “libel laws, securities requirements, charitable registration requirements, franchise laws, tort laws,” and plenty else besides. J. Goldsmith & A. Sykes, The Internet and the Dormant Commerce Clause, 110 Yale L. J. 785, 804 (2001). Nor, as we have seen, is this a recent development. Since the founding, States have enacted an “immense mass” of “[i]nspection laws, quarantine laws, [and] health laws of every description” that have a “considerable” influence on
