No; if you use 6to4, you construct your own 2002::-covered address 
range using your 6to4 router's IPv4 address. You get your own /48 
without having to ask anybody else for it. There's a tunnel involved, 
but the endpoint (IPv4) addresses are automagically assigned (one is an 
address you have installed on your router already, and the other is a 
well-known anycast address).
Using a remote (not directly connected) provider for IPv6 transit 
usually involves a deliberately-plumbed tunnel, not an 
automagically-plumbed one. In that case the remote provider assigns PA 
addresses to you.

Tunnels don't cost real money. They cost pretend money.

There are performance pitfalls with plumbing things over tunnels. I 
personally dislike them; they make me twitchy. Don't let me 
inadvertently colour myself as some great tunnel proponent.
However, my point is that the argument "even if I wanted to, I can't 
use IPv6 because my ISP doesn't support it" should be marked down as 
"false, incorrect, rigourously debunked".
So the argument "I can't get IPv6 addresses because my provider doesn't 
have any to give me" is false, by extension. The trick with that one is 
to find a provider who can give some to you.

I'm not aware of any v6-over-tunnel providers who charge money.

Oh right, that rings a bell. Even with those three extra clicks, I 
still bet my mother could do it.
