Not wanting to work shouldn't be a punishable offense

sure, but if you don't work and nobody needs you around, you shouldn't eat, or live in the woods.

Ignoring that

Tell it to the union, pincushion.

If true, that would be why it is essential to make the means of production public. Private ownership and control over something so essential would place intolerable power in the hands of a few individuals.
