Not really. If there aren't investors willing to buy your stock within a few minutes, there won't be any HFTs willing to buy either. HFTs just bridge that gap in time, for a fee.
You said 3 months. Bridging gaps in time is useful and worth a fee, even at amounts of time significantly shorter than 3 months. I made no claim about all HFT being this, I complained about the metric you were using.
