Many of those types of crops used for feed aren’t really aligned all that well. Corn for instance isn’t going used so heavily in a plant-based diet as it is subsidized (corn is the most subsidized crop in the US). There is also separate food-grade and feed-grade soybeans. 90% of US soy production is going to feed (and not to mention a good portion of the other 10% is going to soybean oil which is not super helpful for a plant-based meat)
90% of U.S. soybeans produced are used as a high-quality protein source for animal feed

Further, they are still getting massive amounts of direct subsidies
The Department of Agriculture has spent almost $50 billion in subsidies for livestock operators since 1995, according to an EWG analysis.
By contrast, since 2018 the USDA has spent less than $30 million to support plant-based and other alternative proteins that may produce fewer greenhouse gases and may require less land than livestock.
Also worth mentioning that beans are not particularly highly subsidized unless you are counting soybeans mentioned earlier.
