What is the ruling on establishing a family recreational park exclusively for families, that prohibits entry to unmarried individuals, provides privacy, and offers services at reasonable prices, especially in a city that lacks such entertainment venues?

The basic principle concerning customs is permissibility, such as building amusement parks, unless there is evidence to prove their prohibition or if they contain objectionable elements. Competing with amusement parks that contain forbidden elements by providing parks free of objectionable elements is considered a righteous deed, as it reduces corruption and provides a wholesome alternative for society. It is necessary to re-evaluate the possibility of preventing objectionable elements by the aforementioned method before embarking on such a project.
