No Andrés, esos videos lo único que demuestran es que no hay nada indestructible, y que la propaganda funciona.
Suponiendo que logres ponerte en posición, apuntar, disparar y guiar el misil...que es mucho suponer entre fuego de supresión, infantes de apoyo, tácticas evasivas, aprovechamiento del terreno ( el enemigo no es tonto y también sabe aprovecharlo), aun así, no es tan facil
Ya que pones a los israelíes como ejemplo:
During the Yom Kippur War the IDF lost many tanks to trained Egyptian crews armed with Sagger missiles.
Since then, the armored corps has developed tactical maneuvering to counter the threat, mostly based on the missile's relatively slow flight and on the ability of crews to see the incoming missile.

Military experts around the world drew several conclusions about the nature of antiarmor warfare from the 1973 Arab-Israeli War. Military authorities believed that the ATGM and its supporting cast of RPGs and recoilless rifles dominated the armor battles on the Suez front, although Israeli tanks and aircraft played a large role in defeating the Egyptian armored reserve. In the Golan Heights area, however, tanks dominated the armor battle until its latter stages, when Israeli armor came up against the Syrian defenses before Damascus.
Therefore, from the analyst's point of view, neither the ATGMs nor the tanks themselves proved to be the decisive antitank weapons. In the United States, this conclusion fueled the debate that resulted in AirLand Battle doctrine. That doctrine's emphasis on a balanced force for the modern battlefield took into consideration the fact that tanks operating alone are, as Trevor Depuy suggested, "more vulnerable and consequently less valuable, than when employed as part of a combined arms team."

Ni otro MBT ni los ATGM se demostraron como el arma antitanque decisiva.
But armor was precisely the problem. First, there was not nearly enough of it along the canal to prevent a crossing on a broad front. Second, while Israel had developed its entire doctrine around armored technology, Egypt and Syria had developed a doctrine for combined-arms operations specifically designed to counter Israeli armored tactics. This involved spearheading armored operations by massive artillery bombardments, followed by large formations of infantry armed with hundreds of portable anti-tank weapons. Of course the Israelis were familiar with the existence of these weapons and their presence in the Arab inventories.
There was nothing particularly novel about them, after all. What came as a shock to the IDF was the sheer number of them. When the Israeli tanks arrived on the scene, whether in the Sinai or on the Golan front, they were decimated. It was a classic move on the part of the Arabs: striking an Israeli center of gravity with as much force as possible.26

Lo que los "shockeo" no fueron los ATGM en si, fue que hubiese tantos.
Todo esto hace más de tres decadas, los misiles han evolucionado, pero los MBT también, y sobre todo las tácticas, que llevan estudiandose más decadas aún.

Aquello les cogió confiado, y en el Libano, bueno, es una guerra, no pretenderas que no pierdan ni un tanque.
De cualquier modo, la prueba más evidente, es que los ejercitos poderosos, siguen comprando MBT, todos lo que les dejan sus gobiernos, si eso fuese como tu dices, sería tirar el dinero. Y podemos suponer que todos hacemos tonterias durante algun tiempo, o que algunos hacemos tonterías todo el tiempo, pero suponer que todos hacemos tonterías todo el tiempo, es demasiado suponer

...y peligroso suponerlo.
Nada es indestructible, pero también, nada es infalible o inevitable.
