All kinds of people in this world, which is what makes it interesting. And yes, some people value showing off, so let them. Personally, I'm on the opposite end of the spectrum, attached is a picture of the highest and lowest trim Model S I've owned: P85D and S60, you figure out which one is which if you can.
Btw, I'm not trying to have a "sleeper car", I just liked the S60 look, so continued with it. I also tend to like clean, debadged looks on all my cars. That said, just because I don't value showing off, doesn't mean I don't think Tesla should offer show off options - if someone is willing to give them money just to show off, why not take the money and put it to good use like furthering technology progress. Porsche is a good example, they have both, functional features (tech package, engine power, etc) and show off features (body kits, gold plated emblems) and there are customers for both.
