Very good point—my feeling also is that Zechariah 14 certainly figures in on the need for some kind of worship center. But any construct must take into account that no further sacrifice for sin other than that of the Lamb on the Cross, whose work was finalized there, never to be repeated again.
While I tend to (want to) agree with you, one cannot deny the prophets. The sacrifices are predicted explicitly. I will have to cross that particular bridge when I get there, but as for now, I cannot teach against the prophets, as EVERY word that ever came out of the mouth of YHWH is true. Let YHWH be true, and every man a liar.
But the people of Israel have not accepted that and won't until the new temple is desicrated. That will happen mid week of the last week of seven years allotted to the people of Israel in Daniel's prophesy of 490 years. Those seven years have not happened yet.
