Well you phrase it as "we are incentivizing" but I'm certainly not on the dev team for any crypto (or exchange for that matter). How could you incentivize those dev teams to make exchanges undesirable for the average user? I think it would be very hard, because a dev would benefit most from mass adoption of "their" coin and mass adoption is currently only possible through exchanges. Self-hosting is either too difficult or too dangerous for most would-be users. In any case you state it as a fact that users should want to give up convenience for independence, but simply by observing their behavior we can conclude that most users don't give a shit about anything except convenience (perhaps because they are already so wrapped up in whatever society they live in that independence is not really possible anyway). Until you manage to change that, persuading users to give up convenience for a higher cost and higher complexity solution is always going to be an extremely uphill battle.
