The “when transporting a large number of people” is quite a caveat. Sure ok high saturation of public transport / walkable cities is probably achievable with high population density, but in rural / regional areas it’s just not possible.
Yeah look, everyone has to find their own way, I’m not trying to make the case that catch & release is going to be better for everyone, and there’s certainly a case to be made for archiving.
The thing that eventually got me was maintaining a big raid array. Lots of heat, power, drives dying every now and again. When it only takes a few minutes to download something and I never go near my bandwidth quota (or it’s unlimited maybe) going to catch & release made a lot of sense. I’m not religious about it but I generally delete things after I’ve listened / watched.
