The bill of rights are about personal freedoms, as is made clear during the discussion leading up to them. All states copied these in some form into their own constitutions, and if you go look at those, most are quite explicit this is a personal right. The claim otherwise is a very recent claim.

Congress around 1982 had the Library of Congress issue a study about this in great depth, with millions of citations to historical documents, which give ample evidence and quotes. You may have to dig to find it, but it's a good read to gain more understanding.

Also the second militia act of 1792 actually required all able bodied men to own guns, and this was the law for well over the following century.

The founders had no qualms about everyone having arms.
