Democracy is supposed to be a good thing, according to elected government officials. Yet these same politicians do everything they can to kill popular businesses. What is market demand if not voluntary democracy, without the winner-takes-all approach to power?

The people love Airbnb. We know this because it is a popular app among both hosts and travelers. But San Diego just passed a regulation that limits Airbnb rentals to primary residences only.

That means that short-term renting is now illegal in San Diego unless you are renting a room in a home in which you live. Rental properties can now only be used for long-term tenants. Renting a secondary property to vacationers is now illegal.

The crackdown on Airbnb-style rentals has the potential to affect as many as 80 percent of the city's more than 11,000 vacation rentals…

"Today's vote by the San Diego City Council is an affront to thousands of responsible, hard-working San Diegans and will result in millions of dollars in lost tax revenue for the City," Airbnb said in a statement to the U-T. "San Diego has been a vacation rental destination for nearly 100 years and today's vote all but ensures activity will be forced underground and guests will choose alternative destinations."

A gaggle of other regulations and fees were also introduced. Property owners cannot rent out their primary residences short-term for more than half the year cumulative.
