I realize your question was in jest,
But, it is a reasonable goal to be able to sleep through chainsaws, garbage truck, leaf blowing, neighbors playing basketball in their driveway, etc.
Blocking outside noise is pretty easy. Most of it comes through windows. Blackout shades plus something else (blinds, roman shades, heavy curtains) do a lot to block noise. Bed placement, choice of room, better windows, better doors, and owning a house with a big yard and a lot of trees all help. If you live close to a particularity loud neighbor, don't pick the room facing them to be your bedroom (or at least position your bed on a different wall). Some of these are not possible for everybody due to location, space or spouse constraints. But, I think most people would have less "chainsaw interruptions" if they used white noise, fans, blackout shades and curtains. Inside noise is a little harder because it can come through vents and interior doors. Door sweeps on each side of a door and foam insulation can do a lot to seal out interior noise (and getting a solid core door).
The only thing that I can definitely not sleep through is work on my roof. I've got most of the other noises insulated against.
It sounds crazy to most folks, but considering sleep hygiene when you buy a house seems pretty reasonable to me.
