So then where's the issue with SSD wear, and wouldn't it be more interesting for people to have spinning drives (for the better ratio of GB / $)?

Is it because of this? So you'd have to print your lottery tickets often enough that a faster drive may help you?

Yes you absolutely want to be farming with spinning drives for the better price to capacity ratio as you mention! (Hopefully in a few years this will change and SSDs will overtake spinning disks in this metric)

The most efficient way to start your farm is to build your plot with a temporary drive (an SSD) and then move it to a destination drive (Spinning HDD) where the actual farming takes place.

The building of the plot is what does heaps of writes and reads and puts the wear on an SSD.

You absolutely can plot directly to Spinning Disk however it is slow and you will really be trashing the heads if you try and plot multiples to the same disk.

The solution is an enterprise SSD with proper endurance. If a consumer SSD doesn't state it's TBW then you can be pretty sure its not very much.

You do trade off for a slower read rate. If the rate of requests coming in is fast enough, your spinning drive/s may not be fast enough to go through the indexes for each one.

Spinning disks are more than fast enough for farming. Many use network connected spinning disks. Tape drive is not fast enough however.
