If I find value in what I have stolen I will try and buy a DRM free copy of the work if it's available.
I have 22k books in my curated calibre library, of those I have read a small fraction of 1% and I have paid for far fewer.
This more or less matches the existing public library pattern.
Authors cannot complain about 'lost income' as I simply would not consume their content anyway if I could not acquire it this way.
