It is absolutely true. The judiciary has no mechanism to _enforce_ laws. Enforcement belongs to the executive branch. Therefore, if the judiciary makes a decision, and the president chooses to not follow the court's order, there is little the courts can do. It can certainly threaten fines and contempt of court to executive officials and even the president, but the president has control over both the DOJ/law enforcement to carry out the ruling as well as having blanket pardon powers.

The current sitting president lead an insurrection against the United States and was not convicted in Congress. We've already crossed the threshold and gone well past the point of Congress acting to hold the executive branch accountable. Now given Musk's threats of financially backing primary candidates against dissenters, there is no incentive to act.
