The flip side is that while basically worthless it’s likewise stupid to accept $100s in costs to *NOT* buy a $5 set of them. That’s my entire point of “the wall costs too much” not being a valid argument when the shutdown was orders of magnitude more expensive. You can change your argument to “well the shutdown was a cost worth paying” but that’s entirely separate argument. For whatever reason many here seem to be completely unable to separate the “cost savings” false argument from a game theory “not rewarding bad behavior“ argument when they are two entirely separate considerations.
Other than your straw man argument that is about costs (hint: its not which is why pelosi offered funding for border security other than for a wall), your analogy falls flat as truck nuts have a fixed cost. Constructing a wall not only has a very fluid cost to it (you can read up on the history of the wall in Israel as an example) but it also has a maintenance cost to it as well so it's very much not a fixed cost.
But allow me to educate you as you seem to be indoctrinated in right wing talking points even though you are supposedly above them.
The reason for democrats not to negotiate with trump, no matter what was offered, is because that's not how this country does it's business. We don't negotiate with terrorist and trump needed to be taught this lesson otherwise there is no doubt he would have used this tactic repeatedly.
Now that you have been educated on the subject, I expect an enlightened guy, such as yourself, will stop with bs right wing talking points.
