If you could see back to any year in history, which year would you choose? You can skip around in time and space within your chosen year, but not affect anything.

The only way I can think of arguing against this is that OPs words were “not affect anything” (emphasis mine). OP does not state that you can’t have an effect specifically on the past. OP says you can’t affect anything.
You would be using knowledge you didn’t have to affect your future.
