Think i have to re-read attunement ^^. Untill now i have treated attunement as an activation cost accompanied by eventual wielder reqs. besides the normal maximum amount attuned items allowed at one time.
On the rarity factor, i like to avoid entire campaigns / lots of playtime going into getting a single item so most are attainable / for sale in my high magic campaign.
The only thing stopping the pc's from getting them would be the req's.
Artifacts are basically one of a kind objects never for sale. Think Excalibur, the one ring, the elder wand, the philosophers stone, those kinds of things. If you do decide to be the kind of cool DM that lets national treasures be bought, based on price progression in DMG (listed sale price do not go to this rarity) artifacts would sell for between 500000 GP and 5000000 GP.
