Linux distros and BSD ports did that since the 90's. When Linux distros had barely a PM or just tarballs, Infomagic sold 4 CD full of libre software. When I had no internet at home, back in the day I bought 3 DVD's of Debian Sarge for 20 euros, about $20. A bargain, it was the price of a hard-cover best seller book.

GB's of libre software, graphical install, 2.6 kernel, KDE3 desktop, very light on my Athlon 2000 with 256MB of RAM. It was incredible compared to what you got with Windows XP and 120 Euro per seat. Nonfree software and almost empty.

And, well, if for instance I could get read only, ~16TB durable USB drive with tons of Guix packages offline (in a two yearly basis with stable releases) for $200 I would buy them in the spot.

You would say that $200 for a distro it's expensive, but for what it provides, if you are only interested in libre gaming and tools, they amount you save can be huge. I've seen people spend $400 in Steam games because of the Holyday sales...
