  *All* of the components of "nuclear waste" are commercially valuable, especially the exotic and hazardous ones.
Which is untrue. Most of it is waste that needs to be dealt with and has no value.

This is just using a different definition of "nuclear waste". What most people mean by this (and are concerned by) is something that is radiologically dangerous and has to be stored for thousands of years, but no such thing exists. There are things that are radiologically dangerous, but they have short half lives and are commercially valuable. Then there are things that "last for thousands of years" (e.g. Pu-239), but Pu-239 is only mildly radioactive and has commercial and government uses as fissile material. In fact, building new reactors is the best way we know of to get rid of it.

What you're referring to ("low-level waste") is this:

https://en.wikipedia.org/wiki/Radioactive_waste#Low-level_wa...

> Low-level wastes include paper, rags, tools, clothing, filters, and other materials which contain small amounts of mostly short-lived radioactivity. Materials that originate from any region of an Active Area are commonly designated as LLW as a precautionary measure even if there is only a remote possibility of being contaminated with radioactive materials. Such LLW typically exhibits no higher radioactivity than one would expect from the same material disposed of in a non-active area, such as a normal office block.

This isn't really "nuclear waste", it's ordinary rubbish that was near radioactive material so people are paranoid about it out of an abundance of caution. And any radioisotopes that are present in it will follow the same rule -- anything with high radioactivity decays quickly. It's no great mystery how to deal with that sort of thing; you store it for a short number of years to let anything with a short half life decay and then you treat it as any other trash.
