A common argument against nuclear power is this:
"We don't actually need nuclear power, because we could potentially use other clean sources of energy".
I am not going to argue against that particular statement, because it is true. We could potentially rid ourselves of nuclear power and have clean energy from other sources.
There are a few implications and practical matters that must be addressed though. So let's take this kind of reasoning a few steps further. What other areas is this statement true for? What more could we potentially be without?
