Capacity drop certainly does occur but it is not nearly as bad as you surmise. An independent company named Recurrent monitors a number of different types of cars and pegs the industry at a whole averaging around 1% loss per year in capacity.
1% a year? That's bullshit. Might get 1% to 2% loss a year (after the rapid initial loss) if you never direct current fast charge AND never charge above 70% or let the charge drop below 20%. But to do that you have to wait forever to charge, which means overnight only, and your range is 50% of advertised.
If you use DCFC and charge to 100% and drop to close to discharged your going to lose at least 35% of your battery capacity by 50,000 miles.

Wondering if the industry battery decay figures are skewed by the rising popularity of cars meaning new cars and batteries that decay more slowly are taking in the lion's share of the stats until market saturation occurs and then the problem becomes more self evident.
Have to take all of this at face value considering all electric cars have their power limited remotely, as showcased in hurricane Irma
Lithium car batteries are no different from lithium cell phone or laptop batteries. Everyone who has ever owned a portable electronic device knows this is total bullshit... and laptops don't sit outside and go from hot to cold constantly or use battery charge to keep themselves cool in the sun.
Its hard to know how comparable it is. Cars also have a lot of cell management features and cooling to promote longevity. It just depends on if you believe the state they are publishing, this used car buyers guide seems like their market position would be enhanced by accurate data so I don’t have reason to believe they fudged the numbers
If you think spending the energy in the battery to cool the battery (aka: using the battery) is going to fix battery degradation I have I bridge to sell you. The cooling feature actually exists so that when you get in the thing and start it on a hot day it doesn't catch fire and incinerate you.
