Kepler did understand the data he had, where it came from, what his laws were claiming, how to verify that the data fits the laws, how the data dis-proves heliocentricity etc, which is really what the article is talking about.
If Kepler's models explained the how and why, why were Newton and Einstein necessary?
Kepler's model predicted the behavior of the planets, and so does Newton's model, but Newton's model is more general, applying not only to planets, but also to apples, cannonballs, trains, and other objects with mass.
Einstein's model is more accurate and precise than Newton's model, especially about the orbit of Mercury. Einstein's model also predicts gravitational lensing (e.g. during eclipses), which Newton's model doesn't.
"Why" questions are very hard for physicists. Generally, when we ask "why" questions, we're asking what prior Event X caused Event Y. But for universal laws, there is no prior event that caused the universal law to be true. The best we get is more generality. Planets orbit the sun for the same reason apples fall to the earth, but we don't know why gravity happens, only how. Magnets resist each other for the same reason the floor is hard, but we don't know why magnetism happens, only how.

Tao and such are merely biological beings serving biological imperative to survive. Educated as they are they are well aware social society expects them to engage in knowledge role-play to barter for food
The recursive non-fractal nature of reality where "function exits" when a human dies naturally fosters signal attenuation and the formation of new spoken traditions among the future generations
There is no propagating our social ways 100 years into the future. We can only propagate our material outputs. The semantics we define to describe something are lost to time.
The provenance to future people was past people; that's all that matters in the future not how we communicated together now
What? He worked meticulously to match the observations.
I don't understand your claim here at all.
