Insects aren't made of meat, they're mostly chitin and lymph. They don't have muscles or blood vessels, turning them into "meat" is not really possible.
"Edible insects contain high quality protein, vitamins and amino acids for humans. Insects have a high food conversion rate, e.g. crickets need six times less feed than cattle, four times less than sheep, and twice less than pigs and broiler chickens to produce the same amount of protein. Besides, they emit less greenhouse gases and ammonia than conventional livestock."
Otherwise beans would be meat too.
Personally, I think fried crickets taste much better than Impossible Burger and the ilk.
I'm astounded that pigs and chickens are that efficient compared to crickets. I was thinking efficiency and body mass would have a close-to-linear negative correlation.
They most certainly do. [1] We could argue about whether the hydraulic structures of the wing count as "blood vessels" - probably not for this purpose, inasmuch as they do not really circulate - but muscles, absolutely.
I mean, yes, insects are arthropods, and there are a few of those (such as salticids, which anyway are arachnids and not insects) who use hydraulic pressure to power some movements. But even for them, that's a special case; mostly they use muscles to move, just like we do, albeit with a very different style of scaffolding.
And, just generally - have you never eaten crab or lobster? What did you imagine you were eating then, if not muscle? Why assume other arthropods would not be constructed in a fashion generally similar to those?

While you are ultimately right, it should be noted that the arthropods are a huge category of animals, and humans are much closer to fish (taxonomically) than insects are to crabs. In fact, insects and crabs are as close as we are to Tunicates [0]: the same phylum, Chordata for us or Arthropoda for them, but different Subphylums (Vertebrata vs Tunicata for us, Insecta vs Crustacea for them).
However, essentially all animals have muscles, from the simplest worms up. Sponges and a few other extremely simplistic animals do lack these, but they are minority exceptions.
So you still cannot create a meat meal with insects.
