I know the Tour has their eligibility requirements and there's obviously a need for that. And maybe I'm being short-sided here in assuming that making a one-time exception for a very exceptional instance of this nature would be unfair to others who have been forced to cut their playing careers short due to medical reasons.
It's just a very inspiring story, I guess, that in the end isn't expected to deliver the ending that many of us prefer to witness... especially considering that just a couple years earlier when Kaymer won the US Open at Pinehurst in such a lopsided fashion - Compton's remarkably inspiring story provided an enormous amount of interest to an otherwise boring major championship.
On a personal level he probably has somewhat of a personal belief that he never totally realized his dream, but considering the overall scheme of things - that couldn't be further from the truth.
Whether he decides to keep trying to get his tour card back or moves on in life to something else, those of us who've followed his story over the past decade wish him the very best, in both health and his future endeavors.
edited to note the misspelling - Erik with a K, not a C. My apologies...
