We don't need any ETF, and the average Joe doesn't even know what is ETF. Go in the street to ask about, you will maybe find 2% of people who know what you're talking about. So I don't see how it can help with the mainstream adoption. Only the Bitcoiners care about ETF with the hope to see any accepted, and it's not to get Bitcoin recognized, it's just a matter to see the price jumping to make more profits.

I agree with your opinion mate since Bitcoin is decentralized asset we don't need those ETF thing for Bitcoin to workout maybe they need Bitcoin for them to workout with the biggest Bitcoin community all over the world. Life goes on with decentralization they may call it as revolutionary currency but still they can do nothing about Bitcoinas people arround the world are united as one with Bitcoin which fiat can't as all countries prefer use their own shit that is why they will find ways to eliminate Bitcoin but the fact is Bitcoin community won't let that to happen.
