What do you think, how many people are ready to sell their goods or services on crypto? Let's say that we have service which help quick and easy to build online store and sell for cryptocurrency. What kind of reasons can motivate people to start a crypto business?
I think that it depend on individual awareness and government regulations on crypto in various locations.
I don't feel like most "small businesses" are ready to take on their daily lives with cryptocurrency-backed purchases. Cryptocurrencies are no stranger to high volatility levels that could drastically change the prices that they may put in their counters. If in any case they will however, they might put some allowance on the prices of their goods which you could otherwise just buy with fiat in a much lower price. So until the issue with volatility is fixed, the latter will be the only viable option these businesses can take on.
