You should read the article to see which symbol actually displays the effects of HFT shenanigans by end of day. (Hint: it starts with K, and it deserved everything it got.)

To see how cheaper liquidity directly enables speculators, read the section "Why Speculators Need Liquidity" in this post: https://www.chrisstucchio.com/blog/2012/hft_apology2.html An example is worked out in detail illustrating the point.

Also, HFTs are extracting far less money than the humans they replace. So if extracting money is what you want to prevent, congrats.
