The thing is, you are absolutely free to use a /c,/d,/e mounting scheme, but you are not shackled to it like you are in Windows. Personally I like to organize my data in one big root (/) file system on my NVME drive and then /data for my bulk storage on HDD and /nas for my NAS shares. I never have any problems knowing where my data is.
BTW, I notice all your complaints revolve around “OMG it’s different” and “OMG the user can choose to do things differently… so complicated”. That is kind of the point of Linux you know?
At some point you just have to accept that it’s different and move on, or decide that it’s too complicated for you and use something else.
BTW, I wonder why people never make this complaint about Apple devices? It also has a hierarchical file structure without drive letters, after all it is also a Unix variant.
