And of course all of the above may be "peanuts" for professional studios, but I am not aware of any hardware/workflow/money/things you can throw at the problem to make the editing and production experience smooth. There are tons of inconveniences, practical barriers, bandwidth issues (and I'm not even talking about network/cloud bandwidth, that's a whole other thing-- even just disk IO, moving stuff around via USB-C, backing up stuff, etc... It's all super labour-intensive and annoying).
Well, if you're editing with proxies (which is really easy with Resolve or Media Composer), the editing experience is really smooth. But that doesn't help for grading or delivery, where you'll still need the full resolution files.
Even with Gen 4 NVMe storage you'll quickly hit bottlenecks at those resolutions.
