The government won't (and shouldn't) fund it until there is defensible evidence it works. Right now there is just anecdotal evidence, and even that is mixed (lots of people have had the treatment without it working). The proposed mechanism is inconsistent with current understanding of MS, attempts by others to duplicate the clinical results have generally not been successful, and the way it is being marketed resembles a lot of past cancer scams, so there's a lot of skepticism on the part of the medical community. There seem to be enough anecdotal reports that it's worth investigating further in my opinion (but I'm not an MS expert). Some experts have suggested the vein blockage might be a symptom of some cases of MS, which might explain the beneficial effect (there's probably at least some placebo effect going on there too, which MS is fairly susceptible to) - but if that's the case it might only be temporary. For the sake of people with MS I hope this does lead to an effective treatment, but the health system isn't meant to fund experimental treatments.
