It is impossible now because several of the "key" 4 or less population (in all grade) coins are in super strong hands. (Strong hands means people that aren't interested in selling even for a profit.)
Now you might say, "ok I'll just give the guy 100 million for it.". That would work on most of them, but there are several coins that are not for sale and the own already has at least 1 Billion dollars so an extra 100 million, while nice, isn't more important than their "hobby".
And ironically the extra 100 million would yield "a coin" but then that person would suddenly be a competitor for some of the other super keys
Another issue is that there are a lot of the super keys that are owned by private collectors and no one, not even top collectors and dealers knows who they are. Again, you could say, "I will launch a 100 million dollar ad campaign to find them." Which just puts us back to reason #1.
NOTE: For those that think 100 million ALWAYS works please remember that the difference between 1 Billion and 1.1 Billion is imperceptible since 1 Billion already includes everything you could buy that 1.1 Billion includes.
