Yeah, i'd have also loved if we moved to an "opt-out" system or one where you are asked to choose at some point.

If we had more than enough organs for everyone we might be able to afford the "luxury" to not adress the issue, but we don't. And compared to the very real consequences this deficit has, it really isn't a burden to reverse the burden through opt-out or at least force people to choose. Not making a choice has just as much consequences, if not more (since it leaves it ambiguous for others that might later have to make the choice for you).

And as you said the majority probably has no problem being a donor, but the default state is a form of apathy/lazyness/ignorance. So like with many other issues a top down approach would be way more effective, compared to putting the burden on every single individual to be proactive.
