on a mac! and remember editing has always been easier as you can work with proxies right up to delivery. Also Final cut was the first to have native support. In post land where we are mostly linux, and scaling up macs cost mega bucks, it was not so rosey. From a post point of view, its much harder to deal with just proxies. I was in MCR, so It was my job to convert from RED to exr/dpx etc. Since it was post, artists had to deal with full res most of the time (can't paint and rotos proxies) Your right it is an over simplification, but decent film stock and decent scanner can get "4k" out of 35mm+, however as you rightly point out you are reaching the limit of the actual res of the film stock (more than quite a few cases) +I used to work with a northlight which overscanneds to 8k then down samples to give the final result.
