Yes, but you avoid the disadvantages of the finit number of pixels. People had the same discussions after the CD players came. Someone found out (probably after reading the Nyquist theorem etc) that they avoided frequency folding by sampling twice as often as necessary to read the music.
If you could oversample the image you would probably avoid the diffuse filter in front of the sensor, the pixel to pixel contrast would increase and you wouldn't have moiré. Remember that picture resultion also is a function of contrast. The disadvantage is the sensor noise from smaller sensors, but some calculations a friend of mine has done indicates that most of the noise in the present dslr's come from other effects than the quantum noise in the pixels.
