That is a basic flaw with 4E. The concept that players MUST be given x number of items of y levels of power so that the game remains in balance. The DM has limited choice in the matter. There are very few non-stacking spells or powers to make up the deficit if this does not occur for some reason.
Doesnt the DMG state something about for a scarce magic item game a DM can simply substitute the need for magic items by giving the PCs a bonus to their AC, defenses, attack, damage, etc. by 1 at every tier and half-tier?
That way you can have magic items be about their properties and powers, instead of about how much function they will add to balance the math. In fact, if you really want to limit the amount of magic items, but at the same time make them at the very least as useful as a character who had a relative "abundant" amount of magic items, you could simply increase the amount of times per day that you could use a specific magic item.
Maybe instead of a different magic item every milestone you could use any magic item that you had, whether it had been used previously or not. That way your flaming longsword, your most prized possession and only magic weapon, isnt a one day wonder.
