We didn't own our own website.
A small company hired a contractor to build the website and set up email. Months later they parted ways. Two months after that the site went down and email stopped. The domain had been quietly moved to a private registration overseas. The old contractor said he didn't know anything about it, but maybe he could look into it. For $250,000. The company spent months with ICANN and the courts, with no website and no email the whole time.
Your domain is the front door to everything. If you don't control it, someone else does.
