Copyright is abused, yes. People want to write anyway, yes. But you need time and resources and space to write, review, edit.

Some novelists spent years collecting rejection slips (e.g. Stephen King; Larry Niven did it full time with a trust fund), which is probably irrational. But with no pot of gold at the end, only the properly delusional or wealthy could justify that investment.

OTOH copyright enforcement isn't that effective, so publishers meaninglessly vary textbook editions yearly, with expiring access to essential online content.
