Next is a geometric property, in particular since the average distance of intervals is infinitely larger than their sizes.

 

Not sure where you get that the "average" distance of intervals is infinitely larger than ther sizes.

 The accumulated size of all intervals is less than 3 over the infinite length.

 True.
 

Hence

 False.
 

there is at least one location with a ratio oo between distance to the interval and length of the interval.

 False. Regardless which interval is "the" interval the distance to that
interval is finite and the length of the interval is non-zero so the
ratio is finite.

 Well, it is finite but huge. Much larger than the interval and therefore the finite intervals are not dense.

They are dense because there are other intervals between the point and the
interval. That's what "dense" means.
