You don’t need a brick and mortar storefront to do business anymore. There are thousands of businesses all over the world that only exist online (and maybe in someone’s home office) which means that every day pre-existing domains are being sold like any other storefront, retail or office space. And just like when you buy a restaurant, beauty parlor or landscaping company from someone else, when you buy a pre-existing domain you have to take the bad with the good.
