I've no issue making my own fun in games, I'd not be fussed if I never achieved Elite status - hey I never managed it in the old one either

I can happily potter about in sandbox games for months on end doing my own thing.
To the offline debate, my personal opinion is actual based on something I've not seen mentioned anywhere yet, which is about what happens if I don't play religiously.
e.g. I play the game for a few months, build up some nice kit and I then decide to do something else with my evenings for a month or 2. During this time when the game world
should be frozen, waiting for me to come back like any other offline game, in Elite-D it's busy changing every second with factions fighting, moving around, areas of space being depleted, and other players who I have no relationship with are messing everything about.
When I come back to my ship there is a very good chance it's now parked in a criminal hideout in the middle of a war zone! Any nice trading routes I had arranged could very likely be gone. I can't just pick up where I left off, I need to relearn the world around me all over again, just like an MMO when you have a few months off.
I've got no issues with online DRM (heck, I own some Ubi$oft games!), my Steam install is always connected. But to have a game world totally change underneath me when I stop playing for a few weeks is not acceptable to me in a
single player game.
