Not required to eat any sugar at all. Your body will actually produce its own glucose if and when needed through gluconeogenesis [1].

Yes it can and it does that when there is an absence of available glycogen provided through carbohydrates, it is not to replace but to support in addition to appropriate sugar intake. It is a less efficient source of glucose, does not provide a large enough amount for exercise and also uses amino acids from muscle to help. Do this long enough and you end up in ketosis which is a whole other kettle of fish.
Why neglect one aspect of our bodies digestive energy systems for just gluconeogenesis. Wouldn't you be better off eating a balanced meal of complex carbohydrates and unsaturated fats. Our bodies have multiple pathways to producing energy, focusing on using only one is silly and not the right approach because it wasn't designed to be that way.
Just because our bodies can survive doing a particular thing in the absence of another, doesn't mean that thing we're absent of isn't required.
Its optimal to solve all the constraints or requirements of needs of the body. But we don't fully understand the requirements as a whole and conflicting information from expertsh. So the rational thing is to rely on the historical data and make judgements on the probability.
