> First, with range decreasing, number of charge cycles per mile, and therefore rate of wear, will increase.

By 10% over 10 years, assuming the worst case of nothing but ultra-fast charging. This seems minor.

Old cheaper cars could be 10% less convenient to use for very long trips. This should not shock anyone.

Rather than an expensive battery swap, sell it on at a lower price to someone who doesn't need 100% range.
