It may be true that the average picture needs only modest resolution, but the required specs for a good camera need to cover more than just the average photo use case. One wants a camera that also covers the extraordinary cases that can capture every bit of detail of a cathedral, verdant forest, striated bird feathers, crystalline rock formations, grains of beach sand, brush-strokes on a painting, strands of a spider's web, etc. Or if one only happens to have a 50mm lens on the camera but then sees some extraordinary but distant subject that needs a 500mm lens, the camera needs the resolution for heavy cropping.
In photography, the cost of storing an image is typically a rounding error compared to the cost of getting to the subject matter for the decisive moment. Storage is incredibly cheap these days. Disk drives for image storage currently cost only about $20/TB (e.g., a n 8 TB drive is about $160). That's a measly $0.02 per GB per copy or 0.10 cents per GB for a main copy, hot backup, on-site cold backup, and two offsite cold backups. So storing images from a 500 MPix 16-bit raw (1 GB) is only a dime. A 1 GB digital image is much cheaper than a 35mm negative and no one ever complained that 35 mm negatives were larger then needed!
Although loading and processing an massive-megapixel image seems onerous, nothing stops a photographer from downsampling images to a lower-resolution if that is all that is needed. Likewise, it's easy to offer a camera with lower-resolution modes (and higher frame-rates and pictures-per-SD-cars performance) so the photographer pick the resolution as needed.
The point is that extra resolution brings extra benefits. And although the need for those benefits might be very rare, the costs of having them available isn't high.
Why give up performance for a once-in-lifetime image just because most images are not once-in-lifetime pictures?
I've long thought that if one's storage costs are too high, one should be more discerning regarding when and how often one pushes the button.
