Owning your domain has the same advantage for element than it would for, for example email. If your company has their own domain for email, but hosts at Gmail, Google can one day decide to kick you off their platform. But, because you have a domain, you can take your business somewhere else.
On the flipside, if your email and personal identity is tied to an @gmail.com address, you are stuck at that vendor.
A second reason is vanity. Full matrix usernames and channels do appear from time to time, and it's nice when it's our own address. (we self-host matrix)
