No I mean the NIMBYism that people present when debating the location of long term storage. What I mean is that the method to create these is not the issue, but rather the public opposition.

What was it Norm MacDonald said? Either you win against cancer or it’s a tie, because you always take the cancer down with you. So cancer is really the underdog here.

Those are not unsolvable problems though, and they stem from political issues rather than the technical problems we still have with the scale of energy storage that we will need with 100% renewable.
And that is not to say that we shouldn’t use renewables, we should just also use nuclear.
