No, I'm saying your own website, with your own domain, with your own hosting plan that you are paying for is part of a long term solution.
Blogger is not my first choice, nor Wordpress. However, if you owned the domain name, and Blogger took you down, as long as you were exporting your content regularly, you could be back up and running on another CMS within an hour, same domain name, thus same "you." Most of the link structure would stay intact if you set up the new one correctly.
If Twitter.com/username breaks your account, or bans you, you can never get that URL back.
