The Muslim world used to have Waqfs of perpetual charitable endowments set up by rich Muslims, Imara (you can search for waqf and imara on google), roads can be built by collecting tolls from road users, see turnpyke roads (on google to see how goo roads were built in the past in the west by private companies). Garbage collectors, electriity lines etc. plumbing can also be built by private companies competing against each other, not protected by the State (as they are now). But it does not have to be in any of these ways I mentioned, people should be able to find solutions themselves without some State Central Planners making problems with their stupid plans. All we need is a good small government ensuring that no haram activities are taking place either in the development and protection of corporations or in making riba appear in any transactions...this will ensure success and victory. The Ottomons used to have free hostels for travellers on roads, they may have been basic but travellers used to get rest, peace and provisions.
