Driving a car is considered a privilege while keeping and bearing arms is a Constitutional right. What's hard to understand about that?
Both are subject to legal constraints
Neither is absolute...What's so hard to understand about that?
Correct.
Although our rights are inalienable, they are not absolute; the government is at liberty to place reasonable restrictions on the exercising of our rights, including the rights enshrined in the Second Amendment, provided those restrictions comport with current Second Amendment jurisprudence:
Like most rights, the Second Amendment right is not unlimited. It is not a right to keep and carry any weapon whatsoever in any manner whatsoever and for whatever purpose: For example, concealed weapons prohibitions have been upheld under the Amendment or state analogues.

Consequently, the issue isn’t ‘whether’ government may place restrictions on gun ownership, as clearly it may, but whether or not proposed restrictions are rationally based, are supported by objective, documented evidence, pursue a proper legislative end, and are therefore indeed Constitutional.
