You don't mention any proposals for how to deal with it so just presenting the problem tells us nothing.
And of course the Rio Grande is only part of the whole border, most of which is quite straight. I'd guess the straight parts is where they'd start the wall.
The biggest point is that a complete "beautiful" wall along the entire border would be a monumental waste of money that could be spent elsewhere. I would suspect that if we took just 1/100th of the cost of wall and used that to fund standard border patrols it would be much more effective per dollar spent.
This isn't a debate over securing our border. This is a debate over how to best spend tax dollars.
