Seems like it would depend on how complete the wall is:

...we find that the border wall expansion caused a decline in migration flows: a 10% increase in the total travel time necessary to avoid the border wall resulted in a 1.4% reduction in bilateral migration flows. This result is robust to accounting for the response of border patrol enforcement, controlling for different types of border walls, and instrumenting the location of the wall expansion using geographic predictors of where the wall was built.

I don't think the best argument is that a wall would be completely ineffective. I think the argument is that it would probably be somewhat effective in reducing illegal immigration but at a very steep cost and with the consequence of being generally bad for the economy, beyond just being immoral.
