I am not sure you understand Steemit. Especially since every valid point to not have banner ads brought up a “yeah, but” from you. One point first, your question above about harmless ads is not the google tied ads you mention below.

 On this platform you make content and 
  get  a share of rewards (4+ million)

  Most of us are here because we hate FB
  and targeted ads

  Crypto people are a secretive bunch,
  so no profiling or targeting ads

  We hate ads

  As for sharing revenues, we are not 
  Youtube

Now, I don’t know if it is permissible to have banner ads on your own blog. If it is, I recommend you work hard to build your following up and sell banner ads on your own posts. That way you could have the excitement of ads (and the money!).

Steemit monetizes content.
