As law first sale would defiantly trump a EULA, you can not sign a contract that restricts a legally ranted right. The solution for companies like AutoDesk is to go straight to a subscription model rather than try to sell software and claim you can resell..

It gets better if you think of it the other way around. The only thing that keeps you from selling as many copies as you want in the first place is copyright law, which gives that right to the author. Since copyright law explicitly does not grant the author the right to control sales beyond the first sale, it is not within the author's rights to prevent such sales no matter what he puts in a EULA.
