Taking short-stack strategy to the -hypothetical- extreme of nano-stacks, it can be shown that such strategy is unexploitable and strictly EV positive. Simply because some folding is bound to happen after the short stack has gone all-in, the deep stacks are collectively in an EV negative position, no matter how many WSOP bracelets they carry with them...
As the shortness of the stacks assumed are well below the minimum buy-in generally imposed at cash tables, this analysis can not be turned into $$$s. However, if one accepts that nano stacks are unbeatable, it is difficult to accept that buying in for more than the minimum would make your game less exploitable.
