Goodness no! Internet usage is rising, and since browsers are helpful enough to add "www." and ".com" if you type a word in the address bar, common word domains like perfume.com, candy.com, etc are extremely valuable because people find them on their own. Most people aren't that savvy and they don't know the difference between the search bar, the address bar, or the bajillion toolbars they have installed.
The supply/demand equation you need to look at is: supply of common english words is fixed while internet usage is increasing. People aren't looking for business.com, they think they're searching for business.
Wouldn't there be an argument to say that in the past people used to put 'perfume' in their browser address bar, and perfume.com etc,
whereas now most people seem to think google is where you 'put stuff', and so aren't the google results for 'perfume' more important than the domain perfume.com?
