Why Are Jews Forbidden to Ascend the Temple Mount?

To the questioner,

It is forbidden for Jews to ascend the Temple Mount in the place where the walls of the Temple once stood.

The area that was once the Temple was sanctified at that time through a detailed process (Shavuot Chapter 2 Mishnah 1), and this sanctity does not depart from the place even after the destruction of the walls.

According to the Torah, it is forbidden for a Jew who is impure to enter the sacred area of the Temple, and the punishment for this is the severe punishment of karet (excision).

Since today we all have the status of being impure due to a corpse (because whenever someone dies within a building, the law is that the impurity of the deceased spreads within certain areas throughout that building, and all those under the roof of that building may become impure - this includes modern hospitals; and thus, since every Jew today has likely been in a hospital, even when they were young, we maintain that they have already become impure, as it is common for there to be a death in a hospital); and the way to purify from this impurity is only through the ashes of the red heifer (and we do not have this ash today, nor can we obtain it due to halachic technical reasons), we have no choice but to wait for the coming of the Messiah when we will have the ashes of the red heifer, and then we will be able to purify ourselves from the impurity of the deceased.

As long as we are still in the status of being impure, it is forbidden by Torah law to ascend to the sacred place on the Temple Mount as stated above.
