Just look at what organized play did. AL essentially re-opened the magic item shop.
So even the official OP doesn't follow those official guidelines
Not just the AL. The official hardcovers, even the 'stingy' ones like Tomb of Annihilation, hand out way, waaaay more magical items than the DMG and Xanathar's assumes.
'5E D&D is a low-magic item game' is simply not a paradigm the official designers for the game adhere to.
