Yes and No. There's Galaxy's Edge, that's the experience that's comparable for all guests (who can afford to travel to Orlando, stay, eat, and buy tickets). Most will never buy a savi saber or a droid, or even be able to ride ROTR. GE is half of the only day of the entire stay on the Starcruiser. If they built GS and no GE than yes that wouldn't be fair. The star cruiser, IMO is a massive upcharge event, (special entertainment, club level concierge and food with VIP entry to Galaxy's edge). That's my expectation to justify the price, I don't think it will blow my mind or be what I would expect from Disney if they really stepped up like they did in parts of Animal Kingdom, horizons back in the day etc. I've already criticized the square hallways from the famous video.I don't think comparing the Star Cruiser to visiting WDW in general is particularly useful or fair.
WDW is accessible to lots of people at varying price points. No, not everyone, but there's low budget options (staying at a dive hotel and taking a shuttle, not getting Genie+), moderate options (lower end WDW resorts), and high end options (monorail resort, upcharge extra hours events, VIP tours, lightning lane, etc.).
Whether one has a low end or high end visit to WDW, they still get to have, for the most part, a comparable experience to everyone else. When we look at the core WDW experience, i.e. spending four days at the theme parks, it is accessible to a large number of people at varying price points.
The Star Cruiser is is a very separate experience. There's no comparable alternative or budget version for people who cannot afford it.
Now that I'm older and I've experienced the high and low, I do think that things like Cinderellas Royal Table (precovid), Chef Mickey's and character dining in general, Monorail resorts and having time to use to the pool without jamming in everything in one or two days because you're a budget of time, tickets etc, buying dolls and costumes and desserts beyond a figurine are in a different league from I experienced growing up. My experience was magical enough that I bring my kids back. But I didn't even know there was a room behind the windows of the castle where you could get pastries and visits/autographs from my favorite princesses without waiting in line. Maybe it didn't exist then, I'd be none the wiser because it wasn't happening.
