When the fourth amendment address unreasonable search, does it means as long as we have nothing illegal?

Does it means that as long as we did nothing wrong or have nothing illegal, then our privacy is protected?|||If it's true that as long as we or they have nothing illegal, then the fourth amendment wouldn't be adopted in the first place. The fourth amendment does not give us the right to privacy, but the right to protect our privacy from being exposed to witnesses. And regardless of whether anyone possess something illegal, the fourth amendment gives direct order to the Court that the actual place must be described and the name of the person or things to be seized and must have a warrant to search and seize a person or a thing.
