Obamacare Unconstitutional

The Washington Times says that fhe Senate on Thursday confirmed Sylvia Mathews Burwell as the next secretary of Health and Human Services in a vote that mixed bipartisan support for her abilities with deep concerns about Obamacare.
The issue here is not whether she should be Secretary of HHS, but the fact that she will be handling Obamacare, which is an unconstitutional law.
The last part of the Fourth Amendment to the Constitution reads, "Nor shall private property be taken for public use, without just compensation." According to the Obamacare law, if a citizen does not purchase health insurance, he will be fined, which is a confiscation of money, which is also property. The question is whether "just compensation"
is provided by the Obamacare law. If the mandatory insurance payments under Obamacare are higher than available previously under a private system, it is not just compensation, even though other services may be provided which are not needed by an individual, such as obstetrical care for a young adult male.
The Obamacare law is obviously unconstitutional based on the Fourth Amendment. When will it be challenged in Federal Court and carried to the Supreme Court?
