I don't want to play devil's advocate on this, but lets think about the Koons video from a different angle.
I agree, she seems like a money-grubbing bitch. But were the Dead not already marketing themselves by the end? There was already a signifcant amount of merchandise out on the market, and GD itself grew into a corporation, with staff/payroll/etc. In his final months, Garcia himself was in an automobile accident, where he was noted in driving his Mercedes (I don't remembe the make, but sure it was not a C-Class). So while everyone was following him around in '68 Microbuses, he wasn't exactly driving around a Gremlin. And there was another blog about Touch, and how bad the video is. Hell, that is good compared to Foolish Heart? Hell in a Bucket?? To me, and my interpretation of what the Dead stood for, those videos didn't really follow what the dead were about.
FOr the guitars, where would you like to see them? Left on shelves, collecting dust? If someone had the means to purchase and play on the weekends, why not. Let me ask - would you rather have a guitar, or a library of music of the Dead? The guitar won't play itself, but the music can always be enjoyed.
