A major problem is that proper reconstruction did not start for a couple of years. The old regime was allowed to take power.
In the immediate aftermath of the war Southern whites would have found resistence harder.
Resistance to what?
The only things anyone required of the South prior to 1867 were acceptance of the Union and abolition of slavery.
They never disputed the former and their reservations about the latter became clear only with the passage of the Black Codes in the winter of 1865/6. Even then, it took a further 18 months for Congress even to buy into granting freedmen the vote. At no time were fantasies about land redistribution even close to being on the agenda.
Especially if confiscation of land was linked to some kind or exile for the planter class.
Please could we come back to earth?
Confiscation was never going to be "linked" to anything because it was never even remotely likely to
happen. See above.
As for exile, please note that even the limited disfranchisements and disqualifications were abandoned by 1872 - at a time when Congress was still heavily Republican, it produced a two-thirds vote in both houses to rescind them. So even the limited sanctions of OTL were half-hearted and short-lived. So where are the votes supposed to come from to exile anybody?
