OK. It's simple. Stealing is stealing. If it's for sale and you don't pay for it, it's stealing.
Side Note: I must be the only Dead Head here on CD. Trading for non-commercial personal use of Grateful Dead shows has always been allowed and encouraged. They allowed tapers into all the shows and if you were a regular, they allowed you to tap into the sound board.
It's still allowed, but has some restrictions. See

And A Stupid Question...
If I pay $20.00 for a CD and I don't want it anymore will the RIAA be upset if I sell it on eBay for $10.00? I'm selling the original.
