agreed, but those details are important but for web-based images or small print I'm not convinced its a huge factor...
Well if the sole purpose of the camera is posting small versions of these images on these boards then it may not be as much of a factor. Even on these web boards the quality difference should be apparent. If you do want to print your images, or just view larger versions, the difference should be very apparent.

I think that with a good tripod, and a point-and-shoot you can still use focus-stacking so it's not really a good comparison to confuse techniques with the overall discussion (IMO).
You made the point that the point and shoot achieves the necessary depth of field without focus stacking. The point was made (IMO incorrectly) that the lens could focus at a 35mm equivalent of f/64. The aperture doesn't change at all and really has nothing to do with it. Extra depth of field in a point and shoot is achieved because the focal length is only...say...1mm. A DSLR shooting the same subject at 100mm will of course have a much smaller DOF. Aperture really has little to do with it.
But I digress, focus stacking is very relevant because this is the method the 35mm camera would use to achieve this depth of field. The point and shoot should have no reason to focus stack because it already had all the dof it should ever need, which was your point.

If you want to print your images to hang on the wall bigger than say 4x7, you'll want SLR / DSLR for sure, If you want "the best" you'll get it... but I was just pointing out that if you're just snapping for web or small print, I think you can do pretty well with a P&S, and macro's are a good example of something they can do well, again within the confines of a P&S camera.
They are good at achieving a wide depth of field, as previously discussed. Macro photography is all about the minor minor details in a subject, for example textures and patterns on individual polyps not even visible to the naked eye. The undeniable quality handicap of point and shoot cameras retards its macro capabilities. Some point and shoots may do macro well in the confines of a point and shoot, but those confines are...well...confining.

Not trying to say P&S is better, they are not, they just have a feature that is unique to them, and, they can do a good job for some applications is all.
Yes for some applications point and shoots can shine, I'll give you that. Some point and shoots are even okay with macro, but as a general rule I just don't think of a point and shoot as a knock em' dead macro tool. It deserves to be said that the single attribute which makes the point and shoot a great macro camera in your argument (small sensor) is the main reason the point and shoot is considered a lesser camera to begin with. When it comes down to it, they just don't have what it takes for the amount of detail macro demands.
I am of course referring to great macro. Those crisp, colorful, awe-inspiring images that take your breath away. The mediocre run of the mill macro could probably be replicated just fine by a point and shoot. There is a level of greatness that just isn't attainable without a DSLR and a macro lens though.
