Justification

Farmers form a "co-op".  Tradesman join a "guild".

Wouldn't it be refreshing to "find" the "right" electrician or plumber or "lawn care" specialist by asking a "guild" for their next "available" member?

Maybe we've got that backward.

Ideally, a guild "polices" its members for honesty or integrity.  It could also make things fair using a "queue" or "round robin" to "assign" work as available.

The uncertainty of an individual finding work might then "disappear" along with any justification to "pad bills".

Even the "self employed" should answer to someone.

It's just good business.
