You can survive or even thrive eating only meat.
You can survive and may be thrive on a diet of total or near total fat.
Eat a diet that consists of just carbohydrates and you would survive for about two months.
This should give an indication of the necessity for carbs in your diet if you eat them exclusively they will kill you in a relatively short time instead of slowly over a longer period .

Do you have any links for that info John?
I’d be really interested to read the stuff on carbs.
Protein, I would agree with (having been carnivore now for nearly 15 months). Not sure about the fat, since protein is essential. But that is a sort lifespan on just carbs (since many carbs come with protein attached), so v curious to see how they tested it...
As for the OP’s question:
Someone with the capacity to produce insulin will do so, all day, every day, whether they eat carbs or not, since insulin has multiple functions.
The body may be able to manage without dietary carbs, but very small amounts of glucose are still needed. This can be produced by breaking down other foods to create glucose.
These are the functions of insulin in the human body

And they are much more extensive (including fat, protein and potassium metabolism) than just pushing glucose into cells.

Insulin made driving many nutrients (including protein) into the cells much more effective. From what I notice, the only successful diabetic bodybuilders are those that are using insulin. The abuse or discovery of the value of insulin in bodybuilding stemmed from diabetic bodybuilders. Only in endurance sports have I heard of a few low carbs or ketogenic athletes getting successful.
From an evolutionary point of view, humans are likely to be healthier without excessive carbs. But too low carbs maybe compromise brain functioning. I am not familiar with brain functioning on ketones though, so I cannot comment on this.

Brain function on ketones is excellent. I have personal experience of this, and it is supported by an increasing number of studies.
This article gives lots of references to studies covering several aspects of brain function helped by ketones - from Alzheimers to epilepsy and diabetic brain fog.

Exogenous insulin for body building is absolutely NOT necessary (unless you have T1, in which case you need the insulin to live), and is a comparatively recent phenomenon in body building. Previous generations managed perfectly well without it. Neither are carbs necessarily required for body building.

Except that we know that people who are eating a diet very high in unprocessed and mostly raw fruits and vegetables, and legumes, with almost no saturated fats are also surviving and thriving, with ridiculous grams of carbs per day and very little insulin (I happen to know a couple of T1s who eat this way, a la MangoMan), which puts a lie to the latter statement.You can survive or even thrive eating only meat.

Even if you are against grains in diet, as humans we have been eating carbs since the dawn of time, as such carbs, sugars and insulin are interconnected and a natural part of our system. What you are failing to appreciate is the amount of carbs and in particular, process sugar that we have been consuming for the last three decades, which is not natural, hence T2D.I personally think that carbs and sugars are a natural part of a person's diet to some degree and therefore the insulin required to balance that out. Many, many people here will disagree. I think our bodies produce insulin to handle these nutrients for a reason but I only have my belief just as those who disagree. I am not aware of any science I can give that supports the point of lesser insulin causing less nourishment other than the knowledge that lack of any other hormone in the body is known to be bad and we don't just tiptoe around those.

On the basis that humans and pre-humans were hunter/gatherers and their diet would have included honey, wild fruits, roots and other forms of wild vegetation, the consumption of carbohydrates would have existed since 'the dawn of time'. Our liver and pancreas functions were created long before human civilisation and reliance on grains as a food source. But it has only been in the last 50 years or so that modern western food has evolved exclusively towards a wholly processed carbohydrate diet, which is spreading unabated throughout the world, and is giving us the chronic diseases we now all expect to get.Hardly "the dawn of time", roughly 10.000 years which is a mere blip on the evolutionary clock. For dairy it is even less time, roughly 7.000 years.
