Most folks (at least in North America) get no where near the recommended level. It's silly to have protein infused junk food, but a shake or protein powder make it a lot easier to get to the right level than remembering to have 3 hard boiled eggs.
In 2026, you can't get a straight answer to this question, because anything protein related is SEO-optimized blogspam (thanks Google).

Protein is made up of amino acids, different sources of protein have different amino acid profiles.
Animal protein matches the amino acids profile we need the best. Whey protein is close, soy isn't bad. You can vary your food groups to balance the amino acids, so if one source is low in one amino acid, you can compliment it with another source higher in another. I found the video intersting and been using protein supplements for near 20 years.
Our biology is immensely adaptable, so anyone declaring you absolutely need some finely decided very specific thing in order to be "be healthy" should be treated skeptically.
With regards to protein specifically: your body doesn't trade in proteins as inputs, it trades in amino acids which cracked off the protein chains you eat. Everything else is just trying to keep the crowd of gut bacteria from making you feel uncomfortable.
