Because the whole philosophy of the #BitAxe is to put a portion of the network's hash rate in the hands of individuals, not just multi-million dollar entirites.

BitAxes mean to empower individuals to enter the mining scene, thus helping decentralize the hash rate.

I can't quote any numbers, but there seems to be a decently sized community of people running BitAxes. That's great, but if all that hash rate could be organized "brought together", I think it can have an even more meaningful impact. One that isn't strictly done in the spirit of promoting and upholding mining decentralization (which, IMO, is a worthy pursuit in and of itself), but one that may have a chance of "collectively" competing against industrial size mining operations.
