I really don't understand how anyone can draw this conclusion. Of all the teams in MLB, the Braves are widely considered one of the teams most set up for long term (5+ years) success.

This "half-assed approach" already got the Braves an NL East title. This "half-assed approach" has the Braves projected to win 82 games in 2019, and they haven't addressed CoF at all. This "half-assed approach" has the Braves set up with almost zero long term payroll commitments and a young core everyone fully expects to get better and better.
There are very few plausible scenarios where a team at the very beginning of a window of contention can trade away a 4-5 win player and still be competitive in the near future.
Freeman will play out his contract as a Brave, and unless he signs a series of short extensions, will be allowed to walk following the 2021 season. They may consider trading him as a rental in 2021 if they are out of the race, but I find that scenario fairly unlikely.
