Bitcoin is for everybody, but we all have to accept it before it can be ours so I conclude that we must first accept bitcoin before we can have access to it and if you don't accept bitcoin you can't invest on it.
But besides all that, there are rules in every country that apply to crypto digital currencies such as bitcoin, which must be obeyed by every community. Because it cannot be denied, that not all countries in the world allow digital currencies such as bitcoin to circulate and be owned by their people.
So in addition to all the freedom that satoshi gives about bitcoin for everyone. But still there are other rules that apply to everyone in their respective countries regarding bitcoin.
And the opinion that you express is not wrong, because to own or invest in bitcoin, you really need a sense of interest, desire and will result in a feeling of acceptance of the bitcoin. So your opinion, all of that is clear and indeed it must be done by anyone who wants to start investing or trading in bitcoin.
