Nearly every community has some form of leakage. When you go on vacation (other than a staycation) you are taking money you earned locally, and spending some of it where you are vacationing.
But for many communities, particularly in the rural areas, locals often go shopping in other towns, or even on Amazon. This is also leakage. But just as you like exploring other areas, you want people to come explore your area. When they do so, they come, spend money, then head home and tell others to do the same. We love that!
The best, most successful destinations import more cash than they export, when they spend money elsewhere. Isn’t it great that tourism can help subsidize your local economy? No wonder tourism is the purest form of economic development!
