This is the number one advocate for the KETO diet telling us that you cannot "eat as much fat as you like and never put on weight".

He says everything that is important in the first 3 minutes.
I have seen a lot of Thomas DeLauer's videos and he is merely an amateur in terms of biochemistry.
He is ignorant of the many complexities of Human Metabolism.
You mentioned Taubes' books which is more informative.
I have read Chapter 10 which has nothing to support your intuitive inference which is wrong.
Instead what is in Chapter 9 may be more relevant;
What’s both fascinating and dismaying about this history is that virtually everyone involved in the diet, weight-control, and health business since the 1960s got at least something important wrong.
This was one of the many factors that worked to make a simple message appear to be complicated.
Invariably these people made some assumptions based either on their preconceptions about gluttony and sloth or on the role of dietary fat in heart disease.
Some were simply enamored by the physics of thermodynamics and couldn’t get away from the idea that what entered the body in excess, whatever that meant, had to be stored as fat.
These biases led them to make significant errors in how they interpreted all this evidence.
The fat we eat won’t stimulate Insulin secretion.
In Chapter 10,
Taubes provided a graph that plot FAT turnover to insulin levels.
It indicate that the Threshold for insulin activation of fats deposition is very low, i.e. 25.
Now I have specifically stipulated,
under very low carb conditions, it will NOT exceed the insulin threshold, therefore fats will be burnt, not be deposited.
When Insulin gets sufficiently low, when the negative stimulus of Insulin is sufficiently draconian, everything changes.
It’s like a switch is thrown.
Above the threshold, fat cells hold on to fat.
Below it, they release their stored fat into the circulation, and the other cells in the body take it up and use it for fuel.
Above the threshold our bodies burn Carbohydrates and store fat.
Below it [threshold], our bodies burn fat.
There are lots of nuances and complex views about human metabolism.
Note I argued, when
one strictly control one carbohydrate intake, and eat as much fats [good ones] as one
CAN, one will not be fat [i.e. obese]. Note Obesity with very high BMIs!
Note the term 'CAN' where the intake of fats is self-limiting in most humans, more so if one is not insulin resistance and on a very low carb diet where too much fats would be nauseating [note the typical indigestion feelings that comes with eating too much fats].
