No it doesn't miss the point. President Trump was not the first to initiate a travel ban in the interest of national security and he targeted only those nations identified by the Obama Administration as primary exporters of terrorism. There was no ban on travel from a huge majority of Muslim nations so there is absolutely zero case to be made that it was a "Muslim travel ban."
Further ". . .in 1972, in Kleindienst v. Mandel, the Supreme Court held that when the executive branch makes a decision to exclude an alien “on the basis of a facially legitimate and bona fide reason,” courts may “neither look behind the exercise of that discretion, nor test it by balancing its justification against the constitutional interests of citizens the visa denial might implicate.” The court reiterated this conclusion just two years ago in Kerry v. Din. . ." (quoted from USA Today)
And the history of it all is quite broad. This article only touches on that history in the 20th Century:

The past six Presidents, with the exception of G.H.W. Bush, have used existing Presidential authority to restrict or ban travel visas or immigration from certain countries.

So with the presence of probability of a massive influx of undocumented refugees, at least some of whom would be terrorists pretending to be refugees, President Trump was not only prudent but within his scope of duties in the interest of national security to issue the TEMPORARY ban that he did.
Such travel bans do not stop home grown terrorists like the Unabomber, Timothy McVeigh, the carnage of the mob wars, and tragedies such as Orlando, Columbine, Sandy Hook, et al, with the most recent being Las Vegas.
But if they stop some terrorists from getting here so easily, why would you object to that?
