You need a domain name if you want to own your destiny. You certainly need one for a company if (a) you ever might want to change service providers, or (b) your service provider might one day go down, out of business, or just plain screw up.

Depending on Google for accessing your site is putting the cart before the horse.

Do you need a great domain name? Maybe not. 1998 was great for people overpaying for domain names. But books.com turned out not to be that important. Or toys.com. Or pets.com. On the other hand, you won't learn much about rainforests at Amazon.com, but you can buy books, toys, and cat litter there.
