A Bolt with 60% capacity can still go 140 miles on a charge. That is still a useful vehicle. What is your prediction for 25% of original capacity? That is when a Bolt would stop being useful for me. I suspect I would want a different vehicle by that time anyway. I generally buy a 2-3 year old car and keep it for 10 years.
In reality we don't know. As you said there are lots of factors involved in battery life including time. Nobody knows what a Li-Ion battery will do in 20 years because they haven't been around that long and the specific chemistry is changing.
