It is worth keeping in mind the words of U.S. Supreme Court Chief Justice John Marshall when he wrote in Cohens v. Virginia 19 US 264 (1821):
“It is most true that this Court will not take jurisdiction if it should not: but it is equally true, that it must take jurisdiction if it should. The judiciary cannot, as the legislature may, avoid a measure because it approaches the confines of the constitution. We cannot pass it by because it is doubtful. With whatever doubts, with whatever difficulties, a case may be attended, we must decide it, if it be brought before us. We have no more right to decline the exercise of jurisdiction which is given, than to usurp that which is not given. The one or the other would be treason to the constitution. Questions may occur which we would gladly avoid; but we cannot avoid them. All we can do is, to exercise our best judgment, and conscientiously to perform our duty. In doing this, on the present occasion, we find this tribunal invested with appellate jurisdiction in all cases arising under the constitution and laws of the United States. We find no exception to this grant, and we cannot insert one.”
That is the heart of the matter...the Court can not invent standing where none exists.
