A lot of tent users on this lightweight forum view " footprints" as unnecessary weight. Yes they help protect the floor of the tent from abrasion and such but at quite a cost in money and weight. Most floor wear occurs where the occupant lies. Many here, including me, will cut a piece of thin Tyvek or polyethylene or Polycryo to about 24" x 74" and use that in place of the much heavier dedicated footprint. Others, again including me, will often do without being of the opinion that the floor material should be sufficiently sturdy on it's own.

I can't speak to the staking issue other than to note that often one can rig the corners to share a single stake rather than using one for the body and another for the fly. Using the tent will sort this out especially if done at home in the back yard.
