It's passing the buck but it also isn't a problem that needs to be solved for several hundred years. And you'll notice I said this isn't a problem as long as we keep researching, aka. not abandonment. My bigger point is that it wasn't like climate change where every day we ignore or don't solve the problem then the problem gets worse (a positive feedback loop). In the case of nuclear, this is not actually true. We also have a substantially larger timeframe to solve the problem. I believe it is naive to also believe that we can come up with a perfect storage solution (long term, doesn't rely on known languages, can handle apocalyptic events, loss of history, and many other factors that only matter when we're looking 10k years out). I think it is a bit naive to believe that a solution we could implement today would be a descent solution. It is better to continue researching and sitting on it (which is safe for now and the next few hundred years. Which is only unsafe because geological effects come into play). No matter what we do you can define it as "passing the buck" simply due to the underlying issue of humans being dumb.
