When prices of something get higher, people naturally try to make more of it to increase supply and cash in on that demand. If a law or zoning regulation or whatever prevents that from happening, that's artificial.
It's not really a statement about whether those laws or regulations are better overall. It's a comparison to other types of investment alternatives which follow the normal laws of supply and demand and have the (lower) earnings to go along with it.
Artificial in the sense of "caused or produced by a human and especially social or political agency" (see https://www.merriam-webster.com/dictionary/artificial).
