We already can't find enough labor:

and unemployment is historically very low.
Is your argument that if we kicked every illegal immigrant out of America tomorrow, that Americans would just choose to starve instead of paying slightly more for food, and farmers would just let food rot on the vine instead of harvesting it?
Oh, they wouldn't choose. They'd just have that as the inevitable consequence. Famines happen; just wishing them away isn't really a great approach.
It doesn't help that these decisions take months/years to show their impacts.
In this scenario, some farmer is going to choose to pay $20/hr for farm workers, and rake in insane profits if there really is a famine. In fact, almost all farms would choose to pay more to collect their food and sell it at a large premium in the case of a food shortage.
And hope that in six months, the trade war hasn't been settled? They won't be paid until the crop matures, and there's a lot of labor before that point. You're also competing with other countries, from whom we already import agricultural goods at reasonable prices.
Again, decisions that lead to famine don't do so instantly.

> In 1990, the average real farm wage for nonsupervisory crop and livestock workers was just over half the average real wage in the nonfarm economy for private-sector nonsupervisory occupations ($11.71 versus $23.19, in 2023 dollars). By 2023, the farm wage ($17.55) was equal to 61 percent of the nonfarm wage ($28.93). In other words, the gap between farm and nonfarm wages is slowly shrinking, but still substantial.
> The share of hired crop farmworkers who were not legally authorized to work in the United States grew from roughly 14 percent in 1989–91 to almost 55 percent in 1999–2001; in recent years it has declined to about 40 percent. In 2020–22, 32 percent of crop farmworkers were U.S. born, 7 percent were immigrants who had obtained U.S. citizenship, 19 percent were other authorized immigrants (primarily permanent residents or green-card holders), and the remaining 42 percent held no work authorization.
