The real trick of 64GB base is to force you to upgrade your iPhone. One of the main reasons why the phone is slow is that there is too little remaining storage space. So when you gradually use up most of the storage space of your phone, you will have to upgrade your phone.
If you're not interested enough in understanding your own requirements and researching and purchasing based on a combination of that and what you are afford then I'm afraid I would call you 'stupid'.
I still think they should've made 32GB base sooner. When you can't do an OTA update (either to iOS 8 or 9, iirc) because the update requires 5GB free space on a device that only has 12GB available to begin with (and app sizes have ballooned), "It just works" no longer applies.
Unscientifically loosely based on the ratio of people that can still make 64 GB work on this website, I would say there’s probably still a fair amount.
I have an iPhone 11 Pro 256GB. I have over 170 games and use 54GB. I hate Offload Apps, so I don't use it. I also hate managing my storage. So 64GB isn't enough for me. Answer on the poll and reply your storage usage.
Apple isn't making the base model just so people won't buy it and buy the version higher. That's just a silly conspiracy theory. I personally know people who bought the base model and like it. That's like saying if a car has what some might consider an under powered engine as the base they're only doing it because they want you to upgrade. That's just silly.
