there are cards that: restore your library, grab cards from exile(out of game, literally), Reverse win conditions, Prevent losing, Generate infinite loops - both deterministic and not(with randomness). Create tokens(sometimes coupled with above) - which provide unlimited resources with a sac outlet. And those aren't fringe cases - for example in EDH format quite a lot of decks win by creating some kind of infinite loop, or by generating infinite resources(or sky high amount of them) So i would argue that resources aren't finite.
