Disc rot is more subtle than you are suggesting: after only a few years, your DVD will develop one bad sector and the movie will stop playing midway through; in a data folder with hundreds of files, one file will mysteriously develop a bad check sum and become unreadable; an external hard drive will work properly for a while and then suddenly start making rattling noises and become inaccessible. I know this because I have experienced all of these types of data loss from the obsolete technologies that you support.

If you want to make the wrong choice to archive your data, then go ahead. But please remember that I did try to warn you as politely as I can.
