simple. TCP wouldn't, and UDP never did anyway.

Fair, lol

Time to load up NetBIOS and... Stuff.

Absolutely. Free flow of information without pay wall allows humanity to collectively build upon itself.

Yes, but it's important to remember that a much (most?) of that work was performed by those with hereditary wealth, under the patronage of those with hereditary wealth, under the patronage of the church, or by clergy who had plenty of free time beyond their duties and no separate need to earn income for housing and food. In fact, one reason to enter the clergy was to gain access to the resources to pursue other activities.

Also, I could see some forms of IP being higher on the list than others. A market socialist setup, where every company is a worker owned co-op, would still have a lot of use for Trademarks. It could be a far less abusive system than the one we have now, but we'd still want it to exist.

Market socialism itself is likely to only be a transitory step, though.

Yes.
