At this point his points are meaningless. He wants to be paid like a GT winner, no team wants to pay GT winner salaries to a 42 year old whose public image isn't all that great bearing in mind next to nobody believes in him. Cobo was at least young enough to justify multi-year contracts, and accepting enough of his own inconsistency to be willing to take less pay than most GT winners would.
I don't see it as sensational in the slightest that he can't get a team for next year. Most teams were already well into their plans for 2014 by the time he became a GT winner and by the time it became clear he would be on the market. Factor in the new higher salary demands due to the GT win, and a lot of teams don't have that kind of room for manoeuvre on the money front. If he were ten years younger, maybe he'd stand a chance, and somebody would take a punt on him, but it might have to be a team less concerned about public image on the doping front, like Lampre or Astana. But they've already got their plans in place. Lampre probably spent a fair amount on Rui Costa and would be looking at him and Ulissi as long term solutions, and with the current world champion they don't need the short term solution that is Horner. Astana have Nibali, and their aging doper quotient is fulfilled by Pellizotti and Scarponi. They don't need Horner either. So then where? Katyusha seem uninterested. Movistar don't need him, Quintana is their future and Valverde is consistently successful over the course of the year. Money is an issue since they've had to spend to lock in Quintana and they've had to let Costa go. You'd have to assume they'd have had more interest in keeping Costa than hiring Horner, because frankly it would be stupid not to. Costa is a guy you can build around for some time, Horner is a stop-gap at best. Trek are completely rebuilding the team, around the classics, and Horner doesn't fit that. OPQS have no room, and Urán's their guy for the GTs now anyway. He doesn't have any place at Argos, and Belkin have already spent a bunch of money buying out Luís León's contract, does anybody think they'd willingly take the risk of Horner following that? Garmin - JV has publicly described his biopassport as "hilarious". Sky have had enough missteps in keeping their zero tolerance policy believable already, and have less than zero need for Horner with Froome, Porte, Henao and co around. Cannondale? Well, they've locked Sagan down, that'll probably put them out of the running on financials, and Lotto, GreenEdge or any of the French teams seem pretty unlikely.
So ProContinental it is? Who would want him there? Certainly nobody who would be willing to pay the salary he demands. Savio doesn't mind aging dopers, but he doesn't have the money for Horner unless he gets even more sponsors. UHC likely can't afford him. Caja Rural can't. IAM aren't likely to want him with their ethos. MTN aren't looking in that direction.
It's a rare thing to see a reigning GT winner go into the following season without a contract without having tested positive, but I really don't see where Horner is going to fit in here. Maybe he's going to have to wait for somebody else to test positive to give a roster spot. He's at the age where he can't just sit home for a year and come back like Linus Gerdemann's just done (and Linus has probably come back for less money than the contract he turned down last year, with his tail between his legs, too), because then he'll be a 43-year-old who nobody believes in.
