While I get high praise from my players for my DMing style (I think they're just sucking up because my wife likes to cook so we almost always provide lunch), personally I wouldn't want to go pro. I would be too self conscious and I tend to be selective of my players to make sure we have a matching style and expectations.
On the other hand, I have no problem with others doing it nor do I think there's an issue with providing a service people find valuable. It's not the death knell of the hobby, it's just one way of commoditizing time and effort. Being a DM can be a huge investment of time, for every hour of play some DM's will spend 1-2 hours of prep time. Especially if you're doing detailed set pieces prepared ahead of time, most professional DMs aren't exactly getting rich.
As others have stated, just because there are restaurants, people still eat at home. Just because there's professional sporting teams, it doesn't mean that people don't play in local leagues or pick-up games. It's not the beginning of the end of gaming as we know it. It's just one more entertainment option for people that desire it.
