I like your analytical approach and you are right: why go to a coworking space when there's not much difference to a real office anyway?

I think the answer for me lies in the flexibility: In a coworking space I can come in or leave at whatever time I want. When I have an unproductive day I can go home at noon and when I feel like working on Saturday I will do so. Offices just have this peer pressure for Mo-Fr 9-6 that you can't evade and coworkers or your manager will raise their brows if you deviate from it. Even in coworking spaces I actually work a very regular schedule, but I just dislike not having the possibility to break out of it.
