It wouldn't surprise me if people typically use more storage on their phone than their computer. The phone should probably have a higher base storage than the base storage of their laptops.
On my Mac I don't have any of these things, it's mostly for programming and some packages. I'm almost always connected to Wi-Fi (except on planes) so I don't really need any photos or videos.
The only people that I see have high storage requirements on Macs are probably video/media creators? As a programmer I'm totally fine with 512GB, but could probably live with 256GB if I wanted to be super lean.
