Vayishlach: Esav Separates From Yaakov, As Lot Did From Avraham

In Bereishit 36:

ו וַיִּקַּח עֵשָׂו אֶת-נָשָׁיו וְאֶת-בָּנָיו וְאֶת-בְּנֹתָיו, וְאֶת-כָּל-נַפְשׁוֹת בֵּיתוֹ, וְאֶת-מִקְנֵהוּ וְאֶת-כָּל-בְּהֶמְתּוֹ וְאֵת כָּל-קִנְיָנוֹ, אֲשֶׁר רָכַשׁ בְּאֶרֶץ כְּנָעַן; וַיֵּלֶךְ אֶל-אֶרֶץ, מִפְּנֵי יַעֲקֹב אָחִיו.	6 And Esau took his wives, and his sons, and his daughters, and all the souls of his house, and his cattle, and all his beasts, and all his possessions, which he had gathered in the land of Canaan; and went into a land away from his brother Jacob.
ז כִּי-הָיָה רְכוּשָׁם רָב, מִשֶּׁבֶת יַחְדָּו; וְלֹא יָכְלָה אֶרֶץ מְגוּרֵיהֶם, לָשֵׂאת אֹתָם--מִפְּנֵי, מִקְנֵיהֶם.	7 For their substance was too great for them to dwell together; and the land of their sojournings could not bear them because of their cattle.

Rashi notes:

and the land of their sojournings could not provide [sufficient] pasture for their animals.
The Midrash Aggadah (Gen. Rabbah 82:13), however, explains “because of his brother Jacob,” [as follows:] Because of the note of obligation of the decree: “that your seed will be strangers” (Gen. 15: 13), which was put upon the descendants of Isaac. He (Esau) said, “I will get out of here. I have neither a share in the gift-for the land has been given to him-nor in the payment of the debt.” [He left] also on account of the shame that [he felt because] he had sold his birthright. — [from Gen. Rabbah 82:13]

Thus, there is an explicit peshat reason, and a separate derash based reason. Those derashot of course have bases in the words of the pasuk. Thus, to point out the partially obvious, וְלֹא יָכְלָה אֶרֶץ מְגוּרֵיהֶם means that Esav could not sustain having to suffer through wanderings and exile, and thus opted out, separating from Yaakov. לָשֵׂאת אֹתָם means bearing them, where is refers to Esav and his descendants, rather than the land. כִּי-הָיָה רְכוּשָׁם רָב is that despite the reward/gift, he will not do it, so as not to have to deal with the debt. Also, on account of the shame from having sold the birthright would seem to come from a reversal of two letters in מִשֶּׁבֶת, to construct miboshet.

There is of course a parallel to Lot separating from Avraham, for the same peshat reason:

ה וְגַם-לְלוֹט--הַהֹלֵךְ, אֶת-אַבְרָם: הָיָה צֹאן-וּבָקָר, וְאֹהָלִים.	5 And Lot also, who went with Abram, had flocks, and herds, and tents.
ו וְלֹא-נָשָׂא אֹתָם הָאָרֶץ, לָשֶׁבֶת יַחְדָּו: כִּי-הָיָה רְכוּשָׁם רָב, וְלֹא יָכְלוּ לָשֶׁבֶת יַחְדָּו.	6 And the land was not able to bear them, that they might dwell together; for their substance was great, so that they could not dwell together.
ז וַיְהִי-רִיב, בֵּין רֹעֵי מִקְנֵה-אַבְרָם, וּבֵין, רֹעֵי מִקְנֵה-לוֹט; וְהַכְּנַעֲנִי, וְהַפְּרִזִּי, אָז, יֹשֵׁב בָּאָרֶץ.	7 And there was a strife between the herdmen of Abram's cattle and the herdmen of Lot's cattle. And the Canaanite and the Perizzite dwelt then in the land.
ח וַיֹּאמֶר אַבְרָם אֶל-לוֹט, אַל-נָא תְהִי מְרִיבָה בֵּינִי וּבֵינֶךָ, וּבֵין רֹעַי, וּבֵין רֹעֶיךָ: כִּי-אֲנָשִׁים אַחִים, אֲנָחְנוּ.	8 And Abram said unto Lot: 'Let there be no strife, I pray thee, between me and thee, and between my herdmen and thy herdmen; for we are brethren.
ט הֲלֹא כָל-הָאָרֶץ לְפָנֶיךָ, הִפָּרֶד נָא מֵעָלָי: אִם-הַשְּׂמֹאל וְאֵימִנָה, וְאִם-הַיָּמִין וְאַשְׂמְאִילָה.	9 Is not the whole land before thee? separate thyself, I pray thee, from me; if thou wilt take the left hand, then I will go to the right; or if thou take the right hand, then I will go to the left.'
י וַיִּשָּׂא-לוֹט אֶת-עֵינָיו, וַיַּרְא אֶת-כָּל-כִּכַּר הַיַּרְדֵּן, כִּי כֻלָּהּ, מַשְׁקֶה--לִפְנֵי שַׁחֵת יְהוָה, אֶת-סְדֹם וְאֶת-עֲמֹרָה, כְּגַן-יְהוָה כְּאֶרֶץ מִצְרַיִם, בֹּאֲכָה צֹעַר.	10 And Lot lifted up his eyes, and beheld all the plain of the Jordan, that it was well watered every where, before the LORD destroyed Sodom and Gomorrah, like the garden of the LORD, like the land of Egypt, as thou goest unto Zoar.
יא וַיִּבְחַר-לוֹ לוֹט, אֵת כָּל-כִּכַּר הַיַּרְדֵּן, וַיִּסַּע לוֹט, מִקֶּדֶם; וַיִּפָּרְדוּ, אִישׁ מֵעַל אָחִיו.	11 So Lot chose him all the plain of the Jordan; and Lot journeyed east; and they separated themselves the one from the other.
