Stardock could give the official answer, but if by 'hard copy' you mean physical media, I don't think Stardock sells those. I know the last Sins of a Solar Empire was 'digital distribution' only meaning download-only (which seems an inaccurate term to me, as optical media -- a DVD -- is digital).
If that's the case, I'm sure you could buy a download, download it onto a thumb drive/external drive or burn it onto a DVD-R to give it to your friend.
