In fact, if warming occurs, the US and Canada stand to net gain arable land and have increased growing seasons.
Of course the counter to that will always be “… but we’re going to have like SO much climate chaos!” which has become the perfect scary, vague and ultimately unprovable argument.
That certain regions are expected to "win" does not fully grasp the impact on our overall economic stability, the systems that keep necessities like food cheap and accessible. Whether you like it or not, the food market is global[1].
"Climate chaos" is not hyperbole.

Calling a flood, hurricane or even several years long drought a “climate related disaster” doesn’t count. These events have occurred since time immemorial.
Every weather measurement deviation from average is not some “disaster” that can be blamed on evil corporations and people driving SUVs.
I'm talking about businesses, yes. Many of which will, as you say, need multiple years to start up elsewhere. I freely and readily acknowledge that this will probably be a difficult process for those businesses. Fortunately, food supply chains are now globe-spanning and de-emphasizing agriculture in drought-prone parts of the US is very unlikely to result in food shortages, much less famine.
We could start more gently by having them pay a fair price for the natural resources they require and are thus not available for everything else that needs water.
If anything, the last few years have shed light on is just how fragile global supply chains are. The war in Ukraine has impacted wheat prices globally.

There's a reason food security is considered a national security issue[1].

"omg lets just move the farms to where the water is"
like you're not talking about growing plants rooted in the literal ground, some that must be cultivated over multiple years to yield quality product.
like we're not all going to be chasing water on a hotter planet with a chaotic climate.
