If I go to an online store and buy a paperback, they will mail me a copy of it that I may keep for the rest of my life. I can read it 100 times if I want to.

Before this law, I could go through that exact process to get a e-book, but then they could come back later and revoke my ability to read the e-book that I “bought”.

Those two cannot use the same word. They are not the same class of transaction. The latter is more like a rental or lease. They both live behind a “buy” button, though.

If I’m told I’m buying an e-book, and the seller later steals it from me by making it unreadable, I have no qualms about obtaining a replacement copy through other channels. I already paid for it; I’m going to have and enjoy it.

You are buying an experience on that night. Similar to buying food at a restaurant

You aren't buying a bad faith argument.

No, you're literally buying an entry ticket. If you were buying an experience, you could sue because the beer was not to your taste.
