Good opinion galadriel'smaiden! It is very plausable s no laughing from me.
With Denethor and his attitude toward Aragorn out of the way, it was up to Faramir to challenge Aragorn's authority, being the new rtuling Steward. he didn't of course because he was a man of good character, and he surely could "feel" that Aragorn was heir of Elendil, with his renown in leading men in battle, the service of the oathbreakers, and his healing knowledge being observed and spoken about.
A 'what if..' scenario is if Boromir had lived and became ruling Steward after the war...
