The point was, you cannot ignore the risks of transportation, if you only have some safe spots to burry it.
And what you linked is still under construction. We don't know yet, if it really works safe long term, or if there will be future costs.

Now I believe it can be done safely, but only if monitored all the time with good care. But that is expensive and humans tend to skimp.
The only real scenarios are deliberate excavation, and a meteor impact directly on the waste repository. Neither of which are particularly likely scenarios.
Are we supposed to hold off on developing the only geographically independent and non-intermittent form of clean energy because of some vague nebulous fear that waste buried half a kilometer deep in bedrock will come back up to the surface and harm people... somehow?
Or rather we do know that the initial promises of reactor safety were also quite overconfident. So people assume the same of permanent storage of the waste.
