Not true - one needs to have a way to read it. And to reference it in time of use.
There are free ways to read, but not to reference. And technically, even the free ways to read are paid for by someone... often taxation.
Reading it at the library can be free... but usually isn't referenceable at time of need. Plus, it's technically paid for by either library membership, a donation system, or the taxbase.
Printing it isn't free, tho some library systems subsidize a certain low volume of printing.
Having an electronic device to read upon away from library is also not free, tho' certain classes of people have subsidized devices.
(On the subsidized devices - for 5 years, my younger offspring was provided a chromebook by the local public school system. Returned at end of school year. Several of my elder offspring's friends have phones provided by the state due to low income, so they have a way DHS and employers can reach them. All that is tax-payer funded.)
