If your definition of a good license is "the terms are as unrestrictive as possible" why not release all software into the public domain?

There's legitimate arguments to be made for more restrictive licenses, even if I don't agree with them all the time.

IIRC, "public domain" means different things in different countries, and can make it hard to enforce as a software license. See https://opensource.org/faq#public-domain

A BSD-style license is probably the closest to public domain while still being easy to read/understand.
