I honestly don't care about a lore perspective, to be honest, and I don't see why my experience in TTK would be ruined by using my old weapons. I love these weapons. Why would I not want to use them? And why should I want to play the game for the first time again? I can make a new character if I want to do that; I don't need Bungie to do it for me. Your argument for making year 1 weapons obsolete is based on supposition and assumptions that I will like something which, presumably, you do. Will I want to try out some of the new weapons? Of course! But I would prefer to decide for myself which weapons I should use. Weapon selection is only one aspect of TTK, which can be experienced fully while still keeping old gear relevant. If year 1 gear had a way to upgrade, there would still be nothing keeping me from trying out the new weapons, but I would have the added benefit of going back to my old favorites if I decide that those new weapons aren't really for me.
