A physical format is a format as well. If you cannot access the physical format, it is useless even if you could have interpreted the data format - if you could have accessed it.

It is really insignificant on which level you cannot access the information, if it is due to the physical dimensions of the medium, the physical encoding of the bits, the way the bits are organized - from sector and tracks on the physical medium, through directory and file formats, to data formats within a file. If the information is inaccessible due to an unhandled format, it is inaccessible, regardless of level.

You may claim to always be ahead, always switching to new media, to new file systems, to new data formats, years ahead of their obsoletion. Lots of people are not following you; they do trust that those backups in the the attic will be as durable as grandmas old photo album.

Another problem is that you might be betting on the wrong horse. Like, I have helped out a couple people who had PC breakdowns, bought a new one, and several months later, when it was time for another round of complete backup, "discovered" that their new PC didn't have a CD burner. So it couldn't create a new backup - and couldn't read back the pile of old backup CDs.

I must admit that I went into that trap myself, although not backup related: A special request made me dig up an old, external adapter, to be plugged into the COM port of the computer. That's a piece of cake, not? But I couldn't find the COM port! The PC was more than two years old, and for over two years, I had never had a need for a COM port, and never realized that it was missing! Later I discovered that the motherboard had a COM header, and in my junk box I found a bracket with a COM socket, so I could have used my current computer. Before I discovered that, I had dug up an old PC wreck from the basement, one with an easy-to-find COM socket.

In an ideal world, no data is lost because physical, filesystem or information formats become obsolete. In an ideal world, no data is lost in conversion from one format to another one. But as they say: In theory, there is no difference theory and practice, but in practice there is.
