Sorry for the cynicism, but I think that distribution simply from holding $ARB is going to be extremely inefficient and a regulatory nightmare.
I’m all for the DAO actually owning the revenue they generate, but turning $ARB into a security (owning the token makes you profit off the work from others) is not a good idea. This revenue could be distributed to people providing important services or stakes to the wider ecosystem instead and allow for sustainable growth. This is especially the case because the OP seems to be suggesting to simply distribute the tokens using disperse, leading to a lot of important revenue potentially being lost for little economic benefit.
$ARB first and foremost is a governance token, and its main role is protocol governance and ownership.. Let’s find a way to direct revenue to the people that create the best value!
