It takes 3 years for your first crop of almonds and 8 before the tree is delivering anything like commercial quantities. These trees have decades of work invested in them and the posts suggestion of ripping out the crop is stupid.
You've never grown anything for commercial profit. To the folks who do, it is most certainly "not stupid" to rip out your crop and replace it with something that would make you more money. I'm not agreeing or disagreeing with the article, but if you grow things, and the things you currently have in the field don't provide as great a profit as something else, it doesn't matter what the crops are, you are going to replace your crops with something more profitable. Done.
I recall very well a weekend where my dad and I took chainsaws to hundreds of nice sized (4-5" trunk) retail nursery shade trees to make space for new ones.
"Can't you get anything for all these? Seems like a $600 tree could do somebody a lot of good instead of turning it into mulch."
"No, I can't get anything for these. It will cost more money in labor to sell these than I would get back. Also, I can save a few thousand in mulch by making it myself."
