That's not the position that Texas took with the ACA
Nonetheless, the plaintiffs in Texas, joined by the Trump administration, urge that, as amended, the ACA’s now zeroed-out individual mandate exceeds the powers of Congress because it can no longer be justified as a tax. More shockingly, they argue that the courts should invalidate the Act in its entirety; that is, that the courts should destroy, not save, the ACA, striking down every single one of its 974 pages because of one supposedly unconstitutional provision.
