Am I reading you corrrectly in that you are saying if there is no right to privacy, then there is no protection against unreasonable search and seizure? If so, I think that is a huge stretch. The Fourth Amendment explicitly addresses search and seizures:

The argument for privacy rights is derived from the Due Process Clause of the Fourteenth Amendment. From Section VII of the Supreme Court Roe v. Wade decision (bolding is mine):
The Constitution does not explicitly mention any right of privacy. In a line of decisions, however, going back perhaps as far as Union Pacific R. Co. v. Botsford, 141 U.S. 250, 251 (1891), the Court has recognized that a right of personal privacy, or a guarantee of certain areas or zones of privacy, does exist under the Constitution. …. [a long list of previous cases omitted].
This right of privacy, whether it be founded in the Fourteenth Amendment's concept of personal liberty and restrictions upon state action, as we feel it is, or, as the District Court determined, in the Ninth Amendment's reservation of rights to the people, is broad enough to encompass a woman's decision whether or not to terminate her pregnancy. The detriment that the State would impose upon the pregnant woman by denying this choice altogether is apparent. Specific and direct harm medically diagnosable even in early pregnancy may be involved. Maternity, or additional offspring, may force upon the woman a distressful life and future. Psychological harm may be imminent. Mental and physical health may be taxed by child care. There is also the distress, for all concerned, associated with the unwanted child, and there is the problem of bringing a child into a family already unable, psychologically and otherwise, to care for it. In other cases, as in this one, the additional difficulties and continuing stigma of unwed motherhood may be involved. All these are factors the woman and her responsible physician necessarily will consider in consultation.
… [Paragraph arguing the states have a right to regulate abortion omitted]
We, therefore, conclude that the right of personal privacy includes the abortion decision, but that this right is not unqualified and must be considered against important state interests in regulation.
A person can agree or disagree with this argument, but even if you disagree and claim that there is no right to privacy, the Fourth Amendment would still protect against unreasonable searches and seizures.
