To address your first question, the common historical reference point for this would be the case of Worcester v. Georgia (1832). In this case, the Supreme Court ruled, essentially, that the Indian Removal Act was unconstitutional and thus the Federal Government must cease their operations under that law. President Andrew Jackson is apocryphally said to have replied: "John Marshall (Chief Justice of the Supreme Court at the time) has made his decision; now let him enforce it." Thus, there are often conflicts between the decisions of a court and the actual implementation of those decisions. To turn to your second question regarding Roe v. Wade, the Court in that decision established a highly structured approach to when states may interfere with a woman's right to undergo an abortion. States that wished to create abortion laws post-Roe generally made their new laws as restrictive as they wanted while still staying within the bounds of Roe's guidelines for federal intervention. For instance, some states established building codes for businesses administering medical services that regulated hallway widths. These restrictions have widely been viewed as attempts to limit abortion providers based on their preexisting infrastructure (many abortions are out-patient procedures, so don't require advanced medical infrastructure such as hallways that can admit a gurney in both directions simultaneously). Finally, the role of federal courts as checks and balances throughout the US is complex, and includes many courts beside the Supreme Court. While the Supreme Court may appear derelict in their Constitutional duties at times, it is important to remember that they are only a small proportion of the federal judiciary system.
