I'm not a history expert, but I think non-voluntary guild might be an oxymoron, and that stopping non-guild members from practicing the craft was part of what a guild did.

To some extent that is true (though guilds and the various powers varied widely across Europe) which is why I said "like a guild" and not a guild.

I doubt that many programmers would agree to 7 years of service under a master either ;).
