Of course you are right with sensor size of m43 compared to FF - sorry for my fault.Sensor size in m43 is actually 1/4 of FF (~225 square mm for m43 vs over ~860 for FF) and as m43 lenses have much smaller sensor area to cover designing and manufacturing quality lenses is much easier, but this is much more of the factor of sensor size than anything else.
But on the other hand you exactly get what is one of the biggest advantages of sensor size - smaller sensors allow for much more relaxed lens/camera designs while still keeping IQ high. Plus given the advances in sensor design today under practical circumstances the differences to FF have shrunk considerably! Sure there are less MP possible and DR is not as good, but end of the day for practical photography the possibility to design easily better lenses/cameras outweigh the relatively small improvements of IQ, DR and better high ISO.
