Why dont they make pumps that have 100-120 psi normaly? Would there be any ill effects from doing this kind of psi with all performance motors?

Yes, there are ill effects from running too much oil pressure. Look at a bearing chart, they usually have a picture of a main bearing that has holes in it's babbit from too much oil pressure. Not to mention that extra work your timing chain has to do. And you can't puch that much oil through a motor, it just squirts out the pressure relief on the pump. Your motor is working extra hard to build all the excess oil pressure, and it just gets sprayed out a relef valve.
