This is something I've thought about as well, especially since I enjoy traveling to Bitcoin-friendly economies. Often, I find myself in situations where I have to choose between high-quality food spots that don't accept BTC and lower-quality food places that do. So when deciding where to go for lunch, which option should I prioritize?
In my opinion, all businesses — like all individuals — will eventually need Bitcoin to survive. As Bitcoin adoption spreads throughout the food industry, businesses that offer the highest quality products will ultimately be the ones most rewarded, forcing others to adapt or risk becoming obsolete. While this shift may take time, those with a low-time preference will benefit in the long run.
Currently, my priorities are to support businesses that either (1) create clean, nourishing food or (2) accept Bitcoin. While these values are equally important to me right now, I believe that businesses which do both will come out ahead in the long term.
