I think we've come to accept the externalities of wind and solar (land area, visual changes to landscape, etc) because the costs of those externalities are so much less than the alternatives. They still exist though. Fusion is probably too late to solve climate change, but I think it's a laudable goal to one day replace renawables such as hydro, wind, and solar farms with fusion.
Yes, indeed. Compared to drastically altering the planets climate, drowning most coastal cities, causing a mass extinction event and disrupting the freshwater supply of billions, visual changes to the landscape does seem like the minor issue.
It does mean that to keep the cost of full systems falling, we need cheaper installation methods, such as rolling out rather than bolting up frames.
