I don't think so. We remain the source of value of Steem tokens, and we will remain the source of that value, whether it applies to Steem tokens, or a new token after Sun forks the crap outta Steem.

When Sun forks, he'll lose the community, and that source of his stake's value. We'll still have value, and he won't.

Hopefully we'll end up on a chain that is actually decentralized, instead of the pretense of it Steem always has been. That will increase our value as well. The tokens don't give us value. We are the value, and where we go, so goes the wealth.
