It's very frustrating to sit down and take the time to write a meaningful and relevant answer (including refs to original work), just to get downvoted without a single comment explaining the reasons of such action. Where i come from, this has a very clear name: trolling. Maybe this is the tip-of-the-iceberg of having a question-&-answer site for topics such as Physics: to be trolled by folks that don't understand what's written. :-P

@Vladimir: regarding your comments about regulators… i think there's something missing, for the VOA (or OPE) uniquely determines the interactions of the theory: this algebraic structure encodes the interactions. What you described above is just a rudimentary way of saying the same thing.

@Vladimir: I know people trying a few different things, but some (if not most) of them requires much more 'hardcore' math — which you have already dismissed above. In any case, the Clay Institute is offering a big prize for whomever can pull this off…

@Vladimir: both of your points above — as expressed — have to do with the same question, the so-called UV-completeness of the theory. This, in turn, is related to Renormalization, VOAs, and so on.

Regarding your first comment above, i explicitly addressed it in my "PS" — in fact, this was the raison d'être for my editing my original answer in order to add the "PS". So, i simply don't understand what you meant. Further, "these points" are not "quite distant" as you seem to think: they are $1/\Lambda$ from each other, where $\Lambda$ is the energy scale of your problem: the more energy, the less apart they are.
