I don’t really know that taking a person’s chosen lifestyle away is gonna make them happier, or that we have the right to force people for the sake of happiness.

Health wise, maybe. Maybe they have more stress because they spend more time in their car due to reallocation of road space from cars to bikes.

You’re dancing around the fact that you are taking from and giving to. It’s a reallocation of wealth from one group to a different group.

The group with wealth taken away loses.
