That's why I have a backup so I wouldn't lose anything if the Kobo goes belly up.

In principle: Yes, but that's where wear leveling comes in.
Also: I use an SSD as my Windows system disk. Why? Because it's much faster than a mechanical disk. I'm not concerned about it breaking any more than with a normal disk.

I think you severely overestimate the number of write accesses.
It's only small chunks of data that is being changed and not very often.
Even if it saves every page turn you'd have roughly 100.000 (that's about the number of writes you get out of a single flash cell) times the number of free blocks of memory write accesses. A block is usually 512 bytes. Let's assume you have 100MB free, that's 200.000 blocks. That would make 100.000 * 200.000 = 20 billion write accesses until the memory wears out.
Let's say you have 1000 accesses per hour of usage, you'd get 2000 years of usage out of it.
And I think 1000 write accesses per hour of reading is quite a lot.
So the reading won't be the big factor in wearing the memory.
Of course if you constantly add and delete books or run updates or whatever that will eat up a lot of the available write cycles.
Again: wear leveling. The real killer for flash is if there's no free space for the wear leveling to use. The fuller your memory is the faster it will degrade.
