oil pump question

There gets to a point in some engine builds where a HV pump and a higher pressure regulation is warranted,and your engine is NOT one of them.
Whenever you ask about oil pumps you will always get those who straight away say" Oh I always use a HV with high pressure". The reason for that is because they simply don't understand where the oil pump fits in relation to the whole oiling system, so they go with what they consider is the safest option and usually it's the wrong option.
Anyone here who is telling you to go to a HV pump , don't know what they are talking about..
