If we make skin and muscle cells when we heal cuts and heal/generate bones after breaking them, why wouldn’t we be able to grow a finger if one is cut off?

It’s too complex to generate all of that. The task of regenerating some skin cells or repairing muscle/bone is smaller than regenerating muscles, tendons, nerves, skin, bone, veins, etc.
That’s some really advanced stuff that even the best hand surgeons can’t accomplish. My husband got his hand caught on a table saw back in 2015 and cut one finger off and mangled 2 more. 5 surgeries later and he never regained full use. A body can only do so much.
I like the analogy of the blind handyman/broken window/broken wall. It’s a great example.
