That's just cash-settled futures. There's no physical delivery, so there's no effect on spot market supply and demand. Cash-settled futures just follow the underlying market.
The OP is talking about futures with physical delivery (offered by Bakkt), which are an entirely different animal. Bakkt, an ETF, or Citi's ADR scheme could all have drastically bigger effects on the market than the CME futures do.
I see where you're coming from. Some people are against it though, because it gives financial giants motivation to hoard massive amounts of coins. It's going to drive up prices like crazy for sure, but it also gives them a very sizable influence.
If institutions aren't hoarding BTC, someone else will. Don't you worry about that.
