A CD doesn’t really mean anything, the license and the physical medium generally aren’t tied. If you break the medium but have a backup you’re not pirating anything. I’d say the primary difference to a CD isn’t more or less secure but physical or not.
Downloading the game also requires an online connection. You’d only need one when you’re buying or selling the license NFT or moving it from one download platform to another, and of course to download the game. Whether you need an online connection to play depends on the game, not the NFT.
