The idea here is to make a clear split between owning and licensing. If the company decides they are selling the items themselves then the items should be repairable by the new owner. If the company decides they are merely selling the rights to use the items then it is reasonable for the user to be unable to repair it, provided the owner (the company) is willing to keep it in working condition.

That should absolutely include wear and tear as well as accidental damage. Intentional damage is an issue, but there shouldn't be much motivation for it under such a system.
