Why? Two reasons. HDD real estate is cheaper than dirt, literally. I think I paid $59 for my last 2TB HDD.

Usually, when I am accessing files, I am doing so from outside LR. You know, posting these, emailing those, putting some on thumb drive for transport. Try doing that with LR Virtual Copies.
I always do all of that direct from LR. As with Elie, the only time I will have a JPEG file on my system (except for those images that can only be created as JPEG, such as from my phone) is while it is being used for some specific purpose. When I send images off to the lab for printing I will keep the JPEG file on my system until the prints arrive. That way if there is an issue I have the "same" file rather than just an identical file. Otherwise I export JPEG from LR and upload/email or whatever and then delete the file from the local disk. For Flickr I don't even generate the JPEG files manually, I simply use the Flickr publish service, and LR takes care of generating the JPEG, uploading it, then removing all the temporary files. I do though use LR for all of my local image viewing needs, if I didn't I would never be able to find half the images I would be interested in. Including the VC's for different aspectratio crops for printing, which I guess wouldn't count as a "different" image, unlike a VC for a monochrome conversion, which I would say was different, I currently have 40539 images in my catalogue. Everything is keyworded and also tagged with IPTC subject codes, which makes using smart collections really easy to sort images by varying criteria, without having to worry about physical locations on hard drives.
The main reason that I do things this way is simple, prior to moving to LR, when I was using a Bridge->ACR->PS workflow I would end up with a RAW file, often a .PSD or TIFF for the intermediate processing, and two or three (or more) different JPEG versions for different needs. What was worse is that at times I might actually end up with differently processed images in different locations, where I had noticed a problem with an image and updated it, but only for the specific version that I was working on. Working exclusively in LR results in just a RAW file in about 98% of cases, and just a PSD/TIFF in addition where I needed additional processing. By only producing a JPEG when it is specifically needed I always know that I am using the most up to date version of the image. Using Export presets, and Publish Collections/Smart Collections it is really easy to throw out a full optimised JPEG file for just about any possible use, with just a click or two.
