As opposed to regular ICE Porsches, you mean, which are excellent value for money compared to mid-market ICE vehicles from other vendors, you mean?
If you're into a Porsche car the Taycan really isn't that bad. If you buy a Porsche, you're not exactly going to buy it for the headroom in the back seats or the enormous trunk.
I just went to the Porsche dealership waiting for my wife's car to get an oil change. I cant imagine why they put a rear seat in the back of those cars. They had a 911 turbo targa or something and the leg clearance of the back seat was 4 inches MAX. I can't imagine ANYONE sitting back there for any length of time.
