This is a serious concept.

I predict that physical art will be huge once robots take all our jobs.

That art needs a marketplace, where anyone in the world can buy it.

The business model:

If a local, physically present person buys it – zero fees – sale price goes 100% to the artist

If someone remote buys it – 30% surcharge – the platform keeps that.

The incentive of the platform is to show the item well, and promote its existence, worldwide.
