Basically all modern airliners with engines under the wing generate torque that tries to raise the nose of the plane. MCAS is to correct for nonintuitive behavior near the limit of the flight envelope when the wing is at a high angle of attack. Most flights never get anywhere near that, and disabling MCAS would not be noticeable.
