Given enough DNA samples, one ought to be able to sort out one’s ancestry much farther back than written records.

I honestly didn’t try to read all that, but there is an interesting thought implied in your comment. That is that to decipher your ancestry, without access to the DNA of everyone on the planet, one needs to be able to identify the geographic location of distinct DNA markers, or haplogroups, to which you can be connected. The only way to do that is to test peoples all over the planet and determine those who have lived for generations past in particular locations, and what their signatures are.

The problem is that in another generation or less, given the mobility of humans these days, there will be no clearly identifiable regional markers left in most geographic regions that haven’t been diluted or masked by emigration or immigration.

If DNA analysis had been refined to the degree that it has in just another decade or or two, we would have only the vaguest idea of early human migrations.
