You would be surprised/disappointed at the amount of abuse the bigger sites have to handle

Interesting, but doesn't fit the context of Stack Exchange blocking Tor. Your example there is regarding a mobile app hotlinking a image of a flower, which seems easy enough to block/fix, while Stack Exchange blocking all Tor users from even reading Stack Overflow doesn't make so much sense.

1 image abused enough, they dig, find the culprit being an app.

Fixes, updating the app, blocking the image, blocking all requests with empty user agents.

1 person abused enough SO, they dig, find the culprit being someone using Tor network.

Fixes, identify the user and ask them to stop, block all traffic from Tor.

-------

Do you propose an alternative fix?
