>i don't drive and the liberty i get from not having a car that i have to park somewhere is huge. better public transport would increase my liberty to move around even further. so this would not reduce my individual agency, but it would increase it.
To your point, who cares about the justification to your liberties? I drive. Yours end where mine start.
how about the car accident statistics?

but what i was trying to point out is that not having a car does not reduce your liberty to move around. it actually increases it. now you can argue the specifics, but you can't argue that without a car your general freedom to move around is reduced. because it isn't. (unless of course you make up some specific example that probably does not apply to the majority of the population. i am sure, for any specific case that you can come up with we can find a workable solution. being that there are cars for rent for the few cases that you need one or something else)
