So what you're saying is, because we didn't see Nagato's stature behind his robe, his lower torso and legs must be perfectly fine? If I have no arm, and I just cover my shoulder with a cloth, shall we can pretend I still have my arm?

Hanzo's explosive tags definitely contributed to Nagato's inability to walk lol, it may not be the only reason, but saying it wasn't a reason at all is simply not true.

The chakra that Nagato absorbed from Bee simply restored Nagato's vitality, it did not mend broken, brittle bones together, and realign Nagato's spine from the placement of the Gedo Mazo rods, it simply just nourished his body. That alone was able to boost the mobility of his body, and Kabuto said that Nagato was still immobile, but he didn't say that it was Nagato not remembering how to walk or run.

Even before Nagato absorbed the chakra of Bee, he appeared behind him with shocking speed for a crippled person, so there are inconsistencies regardless of where you look. Only problem is that what you're arguing is baseless, nothing regarding Nagato being rusty from walking has ever been stated. Going off what we know, Nagato was in even worse shape than Itachi by a landslide, both in terms of vitality and his physical structure, so I doubt the sliver of Bijuu Chakra compared to Bee's overall chakra level was enough to completely heal Nagato of all his ailments.

EDIT: To add onto my last point, if the amount of chakra that Nagato absorbed from Bee was adequate to heal his entire body, why would Nagato have not done it whilst he was alive? It makes less sense for it to work for Nagato as an edo, because he has unlimited chakra anyways.
