"A lot of lps come up all the time on ebay and I generally prefer to get them that way."

And original pressings are, in fact, a limited commodity (in the case of some old folk albums, very limited indeed). It is the contrast of the limitless commodity represented by the download, which effectively makes mass consumption possible with little benefit to the artist, and which removes any demand for re-releases which might actually provide some remuneration for the artists, which is morally dubious.

And if the artists/original labels have not approved their music for download, it's bloody rude as well.
