@taylan >"intellectual property" will be wholesale abolished
You can't abolish something that doesn't exist; https://www.gnu.org/philosophy/not-ipr.html

copyright is only one law that affects software - there are many others - for example patents, trade secret laws, trademarks etc.

>and all companies immediately forced to publish all source code.
That would in fact be a nonfree requirement, as a company shouldn't be forced to publish source code of their private software that they have not distributed.

I guess if it wasn't possible to make software proprietary via copyright, non-disclose agreements, patents, "trade secrets" or trademarks, a requirement that a business must offer the source code alongside the binaries to those who the software is distributed to, to stay in business might ensure that such software is free, but without enforcement, that entails executing of the business, companies will indeed refuse to offer the source code, or provide non-corresponding sources or provide obfuscated sources.

Copyright is somewhat useful in the case of the AGPLv3-or-later, as that foils googles typical activity where they take free software, modify it to add malware and spyware and run it on their servers without distributing it - as google would then need to provide the modified sources to the users of such SaaSS - but without copyright, that wouldn't be possible.
