If you want to store the data, you need to send it to the server with
help of GET/POST/PUT, Andy was suggesting that he could store values
without sending the data to the server, this could be done in a way with
javascript, but the server wouldn't be able to act on the data and you
need to make it somewhat crafty design which is easily broken by the user.

This is why you use sessions, the session cookie can of course be
hijacked, but it will keep track of who is associated with what data.

You could do that, but you would get issues when you have more than one
user from the same ip or a user who change ip during the visit at the
site. I would say the solution is a big step backwards compared to sessions.
