We understand exactly what you're saying. But the point still stands. If you got that piece of equipment early game, and if that piece of equipment got better as you leveled, the game would lose any incentive to get better gear. Removing the need for rewards throughout the game would make for a boring experience.
That answer shows entirely that you don't get what he's saying... What he's saying, is lets say, I do the first dragon quest in Whiterun when I first get there, at for example, level 10, the axe would be as it currently is currently in game, it wouldn't level with me, and it would become obsolete as I gain levels and I would need to replace it with something better. However, if I decide when I get to Whiterun, "naw I don't wanna do the main quest right now, I'ma wander down to Riften and do some thieves guild quests first", so I go do some thieves guild quests, and I get to level 25, and I come back to Whiterun, ready to kill me that dragon. Now I'm level 25, the axe the Jarl gives me has slightly better damage than it would have if I had done the quest at level 10, damage more appropriate to my level, so that its not just vendor trash... again it wouldn't level with me, and it would become obsolete as I gain levels and I would need to replace it with something better, it would just not be useless to begin with.
Edit: Reread his post above yours (which I totally only read the first paragraph of earlier...) and I apologize to DenverRalphy apparently he does want the weapons to scale with him... and I agree that's silly.'
