But the requirement for always having brackets is just plain inconvenient for many. Even C doesn't always require brackets.

>flipping the right number of braces to get that kind of bug is much much harder than indenting a block incorrectly

Maybe, but enclosing an additional statement or more in your brace because you visually indented it incorrectly is just as easy as in Python.

  for (i=0; i<100; i++) {
     do_this_100_times();
     but_this_just_once(); #oops
  }

And if you didn't indent it incorrectly, then it's still possible:

  for (i=0; i<100; i++) {
     do_this_100_times();
  but_this_just_once(); # oops
  }

whereas in Python it's not:

  for i in range(100):
     do_this_100_times()
  but_this_just_once() # correct indentation takes care of it
