Comparing the amount of light on different sized sensors

A mirco four thirds sensor (crop factor 2.0) gathers the same amount of light with a F/2.0 lens compared to a fullframe sensor with a F/4.0 lens since the area of the sensor is four times smaller. If ...

Since larger pixels increase depth of field and sensitivity, why don't we have large sensors with a low number of pixels?

If I understood correctly, the DoF (all other parameters fixed) increases with the pixel surface. So to have a high sensitivity together with a deep DoF, why don't we just have big pixels (and thus ...
