Should the 2nd Amendment Guarantee Access to the Purchase of Firearms?

In Alameda County, California, a zoning ordinance was enacted that required new gun stores to be located at least 500 feet away from any residentially zoned district, elementary, middle or high school, pre-school or day care center, another firearms sales business, or places where liquor is sold or served. 

The catch? There are no parcels within the county that meet the ordinance's requirements. After John Teixeira and his business partners were denied a conditional use permit for a gun store they hoped to open in Alameda County, they filed a federal lawsuit challenging the ordinance.

So, here's the question: 

Should your Second Amendment right include the right to the commerce of firearms?
