Fair, but why?

As you mention, the cellphone for you is essentially a second laptop. There are certainly reasons why having the utility of a laptop in a smaller form factor is a good thing - mostly portability. I actually rarely use a laptop, and never really got used to using a tablet, although I tried one for a little bit. For me, I can either use my desktop, or use my cell phone. My wife has managed to skip the home laptop/desktop altogether, and ONLY uses her phone. This works for her 99% of the time.

So why not ditch the laptop and keep the phone? Or fuck it, keep both? Maybe ditch the carrier service? It's really tricky, once you start actually thinking it through. We apparently are still expected, as human adults in America, to be able to provide a ten-digit number where we can be notified. This is stupid, but true. Ditching the carrier service means paying someone else for a 10 digit number. Yes, you can get them for free, but when you do, what are you giving up? Also, I have had my 10 digit number for 25 years. I'm a little attached to it, because that means that 25 years worth of personal and professional contacts have associated those 10 digits with me. Maybe I don't want to disappear from them, should they want to reach out.

All worth considering though. I wouldn't tell anyone here what to do, because my use cases, preferences, experiences, etc. are not anyone else's. The only thing I believe we should be doing is actually considering these kinds of things more carefully.
