Because even with an mbc fitted the exhaust gasses will usually push the wastegate open at ~24psi (depeneding on the type/condition of the actuator) so the choices are eithet a) buy an uprated actuator with a stronger spring or de waste gate. Dewastegate is cheaper and easier so usually the common choice.
