There continue to be many legitimate reasons why a consumer might not want NAT on their connection. I wouldn't' consider IPSEC the primary one, as even having one side under NAT is generally not an issue in most cases if it's the initiator (further skewing your netflow statistics to even less than the 1% figure as a business case). You've explicitly asked for a CPE without wifi (or one where the SP can disable it). Yes, I know you could buy a wireless "access point", but no consumer will do that. They will run to best buy and come home with a "wireless router". They when they want a "public" IP on _their_ router they will (try) to follow all the guides on xbox.com/slingbox.com/torrentsite.com/ that advise how to bridge the Provider's CPE and run DHCP/PPPOE/L2TP/whatever on their linksys home router. They won't be able to do this with your service. In turn two levels of NAT will break all sorts of stuff, including stuff UPNP commonly handles today, only resolvable via a CPE that can bridge. Stuff far more common than IPSEC. Most other prominent access technologies supports bridging (ADSL, Cable, etc.), it probably wouldn't be too much effort to have a tick box to do the same for your consumer, consider bridging is typically supported in the bottom of the CPE barrel.

Again, you're not in any way shape or form representative. IPSEC IS less than 1% for residential Internet customers in the US and its not even 30% for business accounts. I have visibility into access networks around North America which gives me a sample size that is far larger than required for statistical significance.
Which is fine, but it does *not* justify not putting the check on the tick-list. You merely assign it a lower weight. "Whether to do it" is a cost-benefit analysis. "Not checking to see if you can have it for free" is malpractice.
