Isn't that the same thing as in WoW? Start playing when a new expansion hits and you can raid with veteran players in no time... Bungie's style feels more like resetting, because it's a shooter and they try to keep even the first levels somewhat challenging, even for max level players. WoW is more like 'fvck powercreep, it only goes up from here' which lead to players soloing old raid content that was meant for 40 players... But the logic how gear is handled and how "meaningful" your grind is, is very similiar in those games.
