Bryan Caplan Has High IQ Commenters... and IP Law Hates You

Seems Caplan is in favour of copyright law. I don't know how this can reasonably be enforced. Ironically the one form of IP I am OK with is trademarks - and a weak interpretation at that. For example in Matt Land the following image could never be construed as a copyright violation.

The colour scheme and fonts are absolute dead ringers for
those of the 'Enjoy Coca-Cola' advertising campaign.
However there is an obvious difference in content, so no infringement
of trademark is taking place.

But back to Caplan; do please read his post, but also please read of the comments below. Some smart creative mofos down there. For example, one comment is left by Patri Friedman, scion of Milton & Rose via David, who takes issue with Caplan's position for effectively permitting unsigned contracts, that is un-agreed agreements. Naughty Caplan!
