Ok, lets take this idiocy apart.
1. an options MM is pricing vol, not options - since they are delta hedging, their p&l is not dependent on the terminal distribution, but only on the incremental path of realized vs implied volatility
2. despite large number of buyers and sellers, implied volatility would generally be structurally higher, since the seller wants to be compensated for the short convexity position
3. liquidity in the underlying does play a huge role in this process, since delta hedging requires stock liquidity and signals the market to take the opposite positions
4. the points 1, 2 and 3 above do suggest that you can somewhat predict the expiration price for large delta hedged positions that outsize the underlying market, but it's pretty hard
5. if you have testicles and capital of sufficient size, you can create these situations artificially (i.e. put-bomber pre-08 and such)
6. pretty much everything in the OP is total bullshit
