In this scenario I think the biggest issue with losing an account is the ability to aquire future purchases. But like I said, it's more a matter of principle for some. You own a book, you don't own a digital copy of a book.
On a related note, there ought to be a law that forbids the use of "BUY", "GET", or "PURCHASE" for things you would not in fact own. Instead, they should say "SUBSCRIBE" or "LICENSE".
Those should be for licenses with an end date. "Subscribe" and "license" don't really imply there being a definite end date to your access, but nevertheless informs you that your access is contingent upon the continued existence of the business in question, unlike things you "buy".
This is the direction NFYs should have gone (could still go).
It would be great to be able to resell digital purchases, but that’s only on the consumer’s interest, so will never happen without an act of ${rule_making_body}.
This fundamentally does not work, because being able to copy is such an essential feature of electronic information. Think about it - you can never really "lose access" to information in the computer world unless you purposefully delete it completely, which cannot be realistically ensured.
If it says "license" on the button rather than buy then find another store...
This is not legal advice and is my own personal opinion.
