Compression is simply caused by moving the camera away (=changing the perspective) - you simply choose to use a longer lens to record it If you like the effect, you first choose a perspective (camera position) that alters the apparent relationship of the sizes of the objects in the scene to achieve the effect and THEN you choose a long lens. If you use a shorter lens but a smaller sensor you will record exactly the same "compression" from the same place - same compression from a different lens, so it can;t be caused by the lens

Distance is often determined by other factors, so distance is not the base cause for the perspective in a photo ...

Yes it is.

No, it isn't. A photograph is the end result of many decisions. It is usually the case that the distance is determined by another factor. Which means the perspective is then determined by that factor as well. You wish to speak as if distance can be selected at will, thereby creating whatever perspective one wishes in the photo. That is fantasy for most photos taken. The perspective is determined by what the photographer is able/allowed to do. There are countless situations in which the perspective will be determined by the fact that the photographer probably didn't want to die by trying to stand in a spot that would provide a different perspective. Self preservation determined the distance. Self preservation then constrained the perspective. It is wholly useless to ignore the fact that distance is not something one can choose at will at all times.
