To oversimplify, but catch the essence of, the case for acceleration versus putting a band aid on the status quo, the agreed seems to be that:
Right now x=h people are dying/being substantially harmed/bad thing per year.
Accelerating would increase that to an average of h=x+a for y years, but then decreasing it to h=x-b for z years.
The band aid Bernie would decrease it to h=x-c for w years.
If you think b*z-a*y>c*w, you accelerate. If not, you put a band aid on things. But of course since the latter option is closer to the status quo, we conveniently ignore the magnitude of x in the first place. People endorsing such an option point to the damage done to a and c while sweeping under the rug the damage done to b.
I think b is massive. The group b also includes at least intensively defined pretty much the entire sets of a and c. So the question is less of values (unless an extreme focus on short terms gains is a value in play) and more an empirical difference.
