I've just realized that in some countries in the EU you have to opt in to be able to donate organs in case of death. In others it's the default and they offer opting out.

I see that as an automatic opt in from my POV.

Are there any other such simple things we should be opting in for in Romania, or the EU in general?

I'll start: If you're Romanian you should choose an ONG to redirect 3.5% of your tax to, otherwise it goes to the semi-corrupt government.

Religious European interests have entered the building...

What do you mean?

The reason it isn't opt out and you're in by default. Because the discourse has been poisoned by religious interests claiming it ruins the sanctity of burials or the spirit or some other such bullshit.

Basically this would be the norm far sooner were it not for powerful religious influence.

Oh yea I know lol. Most things come down to religious tradition making us act in nonsensical ways.
