River bet = punt?!

My thinking regarding river bet is any 8 is at the very latest folded by the turn, and most such hands in principle fold preflop. But really the concern here is whether its ok to bet with the straight possible? It's not a value bet anymore because we are really only getting called by straights and very rarely Jx that is overplayed. What do you think? Thanks for feedback!
