D&D isn't just about high magic / high fantasy settings. It has the capability to be used for a variety of campaigns and WotC should have went middle of the road. That would allow the default setting to be a magic is uncommon points of light campaign where items are wondrous and you'll most likely only find them adventuring or very rarely from specific merchants. Then if the DM's wanted, they could give double standard treasure for magic rich campaigns and have the magic shops. Or the DM could abolish all magic items, reduce npc stats by the threshold and poof. Low to no magic. Very easy and more appealing to a variety of gamers instead of just the magic rich gamers.
