I mean, what I could do is purchase a VHS-to-DVD burner and make backups that way. Or, I could buy the Laserdiscs from someone who got them back in the 90's and get all the software / hardware necessary to make a DVD backup from them.
I could spend hundreds of dollars getting DVD copies from the copies I already have, and Lucas wouldn't see a cent of it. I would much rather pay $40 or $50 for an official DVD copy from Lucasfilm, since it'd be higher quality, but if I can't get that there are other legal means of getting my own personal DVD copy of the original versions.
