This question pertains to limits on government action in the US. It is commonly said that driving is a privilege and not a right. Washington state statutes are a bit murky, but RCW 46.20.001 (entitled "License required—Rights and restriction") states that
(2) A person licensed as a driver under this chapter: (a) May exercise the privilege upon all highways in this state; (b) May not be required by a political subdivision to obtain any other license to exercise the privilege
and at various other points, it is referred to as a privilege (especially in dealing with out of state drivers). 42.20.065 however speaks of "an applicant's right to receive a driver's license" and 42.20.095 addresses education regarding "Bicyclists' and pedestrians' rights and responsibilities". (The latter suggests that there is an right to walk down the sidewalk or cross the road, the former suggests a confused view of rights v. privileges but perhaps there's a subtlety that I'm missing).
I do not understand the legal distinction between a "right" and a "privilege", especially, I don't understand what actions are "by right" versus "by privilege". The Bill of Rights does spell out a few specific rights such as bearing arms, being tried by a jury, not testifying against myself and so on. From what I can tell, there is no articulated constitutional right to walk down the street, so walking down to the corner store to buy a quart of milk would appear to be a privilege, not a right. (I exclude the distinct concepts of "privilege" meaning "private communication", also the sense "immune to normal rules" as in executive privilege).
This distinction does not directly impinge on understanding what actions are allowed or prohibited, it pertains to the question of whether the government may restrict you in a particular way. The question is: is there any way to know in advance what actions you have a legal "right" to (the government has limited capacity to restrict your action), as opposed to actions that are simply "allowed" (the government has greater capacity to restrict you). To be very concrete, do I have a "right" to walk down the (public) sidewalk and cross the street, or is that just a "privilege" – and how would I know? I know of the 9th Amendment, also the 10th.
