Does Ubisoft have to honor that Blockchain though by providing you services in perpetuity?

They might if they contractually agreed to honor it. But even if they were inclined to offer such licenses (lets say consumers everywhere demanded it), there's not many meaningful enforcement advantages of shoving NFTs in the mix.

As a consumer such a contract could (including transferability) could exist without an NFT, and be just as enforced by the (centralized) judicial system or consumers voting with their feet.
