It's a really interesting comment which I wish we could explore deeper.
I get the same feelings but about different things. So I know you are sincere. But also, it's cultural and quite superficial. In psychology it's called "identification". An attack on a thing you identify with feels like an attack on you personally.
So for example, for me, attacks on free software, or my "right" to program in a language I choose, or to run a server, feel like actual attacks on my fundamental "freedom" as you say.
In reality though, if the world took those things away, within a couple of months or years I'd have forgotten and moved along with the flow. I know this from the experience of being half a century old :)
Now, if I took away your car, I can promise you'd feel the same in no time at all. Why? I don't own a car, and haven't for about 30 years. I git rid of my car when I moved to London, because private cars are a liability there. One or twice it's been a minor inconvenience. But apart from that I feel as free as ever - I go where I like, when I like, with who I like.... just rarely by car.
Even though I'm a fairly conservative person in some ways, I think we must recognise that many things we cling to as "essential freedoms" are actually just in our minds.
