Cropping does not change anything I've stated. A cropped photo is still a conglomerate of millions of pixels. Maybe not the tens of millions your sensor has, but still millions. If you are cropping so much that your final image can only be printed at native size on a 4x6, or cannot be downsampled, then your cropping way too much, and you seriously need a better camera.
As for detail to draw viewers in, sure, but again...you are either downsampling to some acceptable "web size", or printing, and in both cases, the amount of detail that can be effectively displayed at a comfortable viewing distance is generally going to be significantly less than what your photo started out with at 100%.
Thats unless you do, for example, commercials - first the final crop will depend on the layout, framing tight might make the image unuseable. Second the file is expected to hold up when zoomed in, because you have details from the overall image enlarged in dead spaces. The whole image to set the mood, the and enlargements to sell the actual product or draw attention to specific details. Enough resolution is approximatly when you can go from a full length shot with some scenery to a closeup of a piece of jewellery...
