The original idea was not to use celestia in combination with etherum, but the original idea was that you have this licliencide execution. So why we're not sing solely on this is mainly because yet it's one use case for celestia, and it's not the only use case. If i had to choose between like one or the other, i would rather try to build only the deroll up case,. The roll up on top of celestia case could be potentially much more scalable than the one that uses the therem my term.
