Why doesn't Make Table View allow me to then Append the rows to a table

Took a feature class and made a table view from its attribute table, using Make Table View.
Tried to use that table view as input to Append, to append to a table. Failed with Error 000573: The input and output must both be of the same type.

Why didn't this work? If it should not work for some reason (it looks as if it should), why did the Append tool let me try to run instead of flagging the error?
