If they released the digital copy at the same time, we'd all be waiting another 3 weeks to play it because I'd imagine it takes extra time to get the disc copies made and distributed to the shops etc rather than just uploaded to an online store - so then you're punishing the digital only crowd when they could have the game already... So would they get free stuff just for the "inconvenience" of waiting? No, not at all.
Digital gamers have paid a little bit more for the deluxe version over the basic, and I'm pretty sure there was some info on the deluxe dinosaurs being released as separate paid dlc which the physical copy crowd can buy - so why is it that this should be free just because you are waiting a bit longer for a disc because you want it rather than digital? You absolutely don't have to wait, you are choosing to, that's down to you and your choice as a customer, I can't see you are being forced into anything so you aren't entitled to anything for the "inconvenience" of your own choices.
And for the record, I'd also prefer a physical copy, but am choosing not to wait for it because at the end of the day... It's the same game right?
