Things that could have been done to help Shmi Skywalker:
republic credits. He could have found a more suggestible businessman and “forced”
them to trade currencies so he would have enough to buy Shmi.
They could have
knocked Watto down and taken Shmi with them. By the time watto woke they would
be long gone, probably with enough tech to remove the chip or disable it (in legends it’s established
that the chip’s signal only works on the planet so when the slave leaves orbit
they are safe whether or not the chip was removed or inactive.
have hired someone to strong-arm Watto into freeing shmi (or done it themselves)
have gone straight to the Hutts to make a deal with them. Something like, make
this guy free this slave and this jedi will owe you one. We know the jedi have
no problem helping slavers when it serves their own interests.
he could at
least have bought some protection for her, like hiring someone to keep an eye
on her. she was only left with some credits because Anakin gave his to her. No
one else made any attempt to, at the very least, improve the poor woman’s life.
