If you check citations, you'd find the sentence preceding my excerpt on barriers to entry:
"Because barriers to entry protect incumbent firms and restrict competition in a market, they can contribute to distortionary prices and are therefore most important when discussing antitrust policy."
Antitrust policy then links to a page on competition law: "Competition law is the field of law that promotes or seeks to maintain market competition by regulating anti-competitive conduct by companies." [0]
So yes, I'd downvote you if I could, but HN doesn't allow downvotes - which is honestly pretty fitting in the context of this conversation.
