I don't think it needs to be mutually exclusive. I have a great relationship with several local dive shops in our area. One frequently rents me pool time when I need it at very reasonable rates. Another either loans me gear or rents it to me at very low rates as needed for classes. Both shops are very successful, even in today's environment. They are, in part, because the owners don't see me ... the independent instructor ... as "competition". Instead they see me as a potential revenue source ... producing students who consistently continue diving and need to purchase equipment and services I don't offer. And because of our mutual business relationships, the chances of them getting some or all of those student's future purchases is reasonably good.
I'd like to see both of those shops continue well into the future ... and, frankly, their chances of doing so are pretty good.
Dive shops are often their own worst enemy when it comes to business transactions ... not so much because of price, but because this is an industry where people running dive businesses frequently eat their own. The dive shop of the future will be the one who doesn't see independents or online retailers as competitors so much as potential business partners ... their real competitors are other recreational activities that vie for the discretionary dollars of their customers.
Right now ... in my area ... the dive shops who are consistently doing well in a difficult environment are the ones who create an environment that welcomes partnerships, offers value-added services like free seminars on topics of interest, and seeks out mutually-beneficial partnerships with other scuba operations like independent instructors, charter businesses, and other dive shops. Those who have taken a "divide and conquer" approach, or who insist on "loyalty" from their customers are not doing so well ... I can think of a couple locally that are, frankly, on the verge of going out of business because that attitude tends to make their potential customer base go elsewhere.
The dive shop of the future ... perhaps it's the dive shop of the present who seeks out ways to make people want to do business with them in spite of all the obstacles thrown in their way. I think as long as people are spending money on scuba, those shops will always be around ...
