> So if something is complex we shouldn't or can't build it?
We were discussing why fusion plants are necessarily more expensive than fission plants - not whether they can (or even should) in principle be built.
> Energy is needed to perform electrolysis to create hydrogen. What about the energy needed to mine uranium? I think it might require quite a lot of effort, particularly once supplies get harder to reach and extract.
I listed many other energy costs - including some uranium to breed tritium.
> The radioactivity is much more short term than fission.
Sure, but that still means decades for tritium and centuries for the neutron-bombarded materials - more than enough to make it as big of a problem in our lifetimes per kg, just with many more kg of waste from fusion.
