  I maintain that I see many cheap variants of Venetian blinds, which impacts their usability. I have never seen a cheap roller blind that doesn’t still work relatively well
  The privacy due to angling the blinds is a strong argument, and I’m willing to concede that this promotes some good use cases for Venetian blinds
context: All of these problems are solved by not buying literally the cheapest blinds.
  Spend a bit more and you will get nice looks, better light blocking, good materials, and opening/closing mechanism that feel smooth.
  As for benefits over other blinds: you can control the amount of light that comes in.   You cannot evenly block out 50% of the light with a roller or traditional curtain.  You also don't need to wash them. >
  
  Some strong arguments here, but I often see so many cheap, ineffective Venetian blinds, whereas I can hardly say the same for roller blinds, which are often very effective at their job. 
  It’s no use having all the functionality of the Venetian blinds as a purchase motivation, if people get the cheap installations which hardly let those functions work. 
  I am now on board that an upper end Venetian blind, could have the same benefits and more, of a standard roller blind >

  Thanks!
  Glad you changed your view (even if a little bit).
  I actually agree with you that CHEAP plastic blinds are horrific and worse than even the cheapest curtains.
  But quality blinds, do offer a lot of benefits. >
  
  if they are made from cheap plastic then you have the dollar store variant of them,  complaining that the cheapest variant of a product isn't as good is a false comparison,

  buy some decent Venetian blinds and they will work for a long time and actually work well.

  and a Venetian blind can give you light at an angle, allowing the room to be well lit without allowing someone to look inside   essentially a dimmer switch instead of an on/off
