I'm a layman when it comes to this but doesn't that mean the amount of "channels" is still severely limited? Someone mentioned 220million transactions annually.

I'm a layman when it comes to this but doesn't that mean the amount of "channels" is still severely limited? Someone mentioned 220million transactions annually. Even if those channels only open and close the balance once a year that's very little it seems. Or can there be more than 2 owners of a channel?
