Offices, bridges, tunnels, etc are commodities. even houses are built with the expectation that they will outlive the tennants. there's not another tennant that can move into a football stadium. a stadium's ability to maximize revenue (and team performance) relates to designs, ammenities, sellability, etc.. i completely agree that the GA dome doesn't scream "archaic" like the Vet, Riverfront, 3 Rivers, etc did at their end...but it's realistic that it might in 10 years. If Arthur Blank's business plan says "if we build x, we can sell y (plus meet modern customer experience needs, make the team more attractive to FAs, etc)", then so be it. Let the parties do business and it'll work out.
