Why is the World Possible as a Perpetuum Mobile?

One could understand this using the example of iodine nitrogen. This substance decomposes into its components at the slightest excitation. A significant amount of energy is released. The energy leaves the system in the form of heat, increased pressure, and radiation. A reversal of the reaction does not occur spontaneously. As you can see, everything is mortal (except stupidity).
It would be different if the chemical could be tightly enclosed in a pressure-tight and energy-tight chamber. The substance would heat up considerably, and the pressure would increase enormously. According to the law of mass action, the reverse reaction could then occur.* Such a chamber is hardly technically feasible. Such energies can perhaps be found in a star, neutron star, or black hole. In a perpetual motion machine of the second kind, no energy is allowed to leave the system. This is how I would explain the world as a perpetual motion machine.
Additionally: In very large quantities, the unlikely becomes more likely. This is how I explain galaxies in equilibrium. The equilibrium cannot be fundamentally changed by any force. You can't destroy an infinite number of tennis balls (they don't fit into any finite world) if you can only destroy a finite number in a non-vanishing amount of time.

*An irreversible exothermic process in a closed system increases entropy until thermodynamic equilibrium or until an activation energy is required for further reaction. But then the entropy no longer changes.
