Agreed. But there are reasons it is perfect legal for a library to digitize physical copies they own, and then can lend, also under the legal name of "Controlled digital lending". Clearly public domain works are fine, and US law also has exemptions for preservation where a new copy cannot be obtained at a "fair price", and perhaps some other things. So making it seem as if all "controlled digital lending" is not allowed under current law, even under the description you give, is not that simple.
