'Regulation of Art' isn't regulation so much as a dynamic that hinges on cost of production and niche market interest.

Take for example a new site that wants to install a public sculpture, the leads for the site are not going to just prompt 'Public Art' and 3d-print. The stakeholders and relationships involved are a real thing and influence.

Personally as someone who loves playing around with AI-Art its potential variety is still very small compared to the scope of creative work that human's get up to. Interested people will maintain their sensitivity to the difference.
