You see this barrier as a "monument" to Trump. I see it as a monument to stupidity on both sides. Remember, many politicians, Democrats included, were for the barrier before they were against it. Because Trump and no other reason why. There is no moral high ground to be had here. They only oppose it because Trump supports it.
Now, you say it won't solve all the problems of illegal immigration. I agree. However, it if can stem the tide at this point, it's a worthy endeavor. Once you get control in place, you can look at the rest of the problems like overstaying visas for example. Perhaps even an amnesty type situation comparable to the Gang of 8 idea some years ago. Or what Rubio proposed during the 2016 campaign. We've reached the point where amnesty cannot be simply dismissed. Eight figures of illegals are in the country right now. You cannot and will not ever deport all of them. Even the most ardent supporter of action against illegals will admit that.
Remember, this isn't a fight about putting up a barrier along the border. It's simply an extension of the Never Trump agenda that's been going on since 2016. Just a new battleground so to speak.
