Literally 20% of the lines of the poem are spent saying there is NO discernable difference in how much the two roads have been traveled. Another 10% are saying the roads both look great and he'd like to travel on each of them. Then the conclusion -- the only bit most people remember -- is explicitly said to be what he will say "ages and ages hence". There is zero indication that's what he actually thinks at the time the poem is written. The argument in this article isn't some sophisticated take on the poem. It's just a straight literal reading of what the poem says. The only bit that's in any way fancy is recognizing that when the poet says he's going to say something (instead of just directly saying that something) you might have to think about why the poet is putting things in that very roundabout way.
