Please elaborate. We're talking about a situation in which I grant a
licence for you to copy and use my work, in exchange for something I
desire from you. In the absence of a contract, this is limited to me
effectively saying "You may copy and use my work if and only if you do
XXX".

If you do not do 'XXX' then you may not use my work.

Are you saying that there are things which I may not ask for? Could you
elaborate?

Certainly criminal law prohibits me from actually inciting you to murder
by really asking for the sacrifice of your first-born; I'll grant you
that one.

But what's wrong with postcardware, where I ask you to send me a
postcard in exchange for permission to use my work?

What's wrong with shareware, where you have permission to copy my work
and use it for evaluation purposes, but you're asked to pay me if you
continue to use it?

What's wrong with a licence which requires you to bathe daily in
creosote in order to receive my permission?

What's wrong with a licence on my software which requires you to
relinquish copyright on any musical score you ever write?

What's wrong with a licence which requires you to release any unrelated
software you ever write under the same licence?

It may be increasingly unlikely that you'll _accept_ some of the above
licences, but there's no fundamental problem with them.

I need a contract to force you to do anything; this is true.

Without a contract, all I can do if you don't abide by my conditions is
observe that you don't have my permission to copy my work, and hence
that if you do so you are committing a criminal offence.
