This is how the game was written, and maybe how it was actually played at Gary's table, and presumably other tables. However, I was there in 1980, too, and a lot of this stuff just wasn't true IME. The game may have assumed a ton of henchmen and hirelings, but I never actually saw them in play. Many, and perhaps most people handwaved spell components and rations just as casually back then as they do now.
Of course, we've been through all this before with Quasqueton's many interesting threads. T. Foster also had an exceedingly brilliant post awhile back about how the Player's Handbook's advice for players planning a dungeon expedition really applied only to the Lake Geneva campaign, and not the game as it was played by the rest of us.
Without trying to hijack the thread too badly, I'm just saying that 4e is really not that big a change from what I was doing in 1980.
