That just means a different set of people can get stuck having to rename, i.e. whatever group doesn't include you. How confident are you that (assuming your project thrives) you'll be around in 10 years and have the project's best interests at heart?

Even the nicest and best people can change for the worse. One of the reasons to go for some foundation-like entity owning the name is that you can equalize out across multiple people in a meritocratic, democratic, demarchist, or whatever else process.

And even if you're incredibly sure you won't become a bad person: what happens if life hits you hard? A relative becomes disabled and you need money to care for them? Will you sell the trademark?
