My bet is that in the next couple of years we're going to see SpaceX start to move into in-orbit infrastructure: habitats, refueling depots, servicing stations, orbital assembly yards and so on, all the way up to massive mining systems.
Having infrastructure in orbit for say, refueling, reduces potential costs for certain space activities significantly and nobody else really has a good story for lifting the mass needed to build that stuff. Heck, spent Starships might even make decent core components for some of these facilities. Why deorbit them and shipbreak them after their serviceable lifespan when they could be kept up in orbit and comfortably house a dozen humans?
Yeah, I think there are a lot of people that are missing how much of a perfect bottleneck launch capacity is. Lots of companies putting the proverbial cart before the horse, saying "I'm not gonna be the space launch company, I'm gonna be the space hotel company" – but that's not necessarily how things are going to play out in space. In fact, we've already seen this happen with "internet satellite constellation companies". Sure, SpaceX could've just sat back and launched OneWeb's sats for them, but instead they built Starlink and they'll probably eat OneWeb's lunch.
With regards to using Starships as infrastructure, I actually saw a pretty cool idea[1], where you attach either two Starships together (or many to some other central structure) via cable/structure and use thrust to spin up around the center of mass, creating artificial gravity through centripetal force. The linked YouTube video talks about going to Mars/etc with this, but no reason it couldn't be a space station in orbit around earth.
