I see this myth too often in this community, the minimum recommendation for sedentary adults is 0.8g per kg of body weight, not for people who want to increase muscle protein synthesis (AKA building muscle) and also not for active individuals as their body also requires more protein for recovery.
When you look into the science you can find different recommendations, I personally aim for 2.2g of protein per kg of body weight, because of this paper: "In a large meta-analysis, protein intake was shown to promote additional gains in lean body mass beyond those observed with resistance exercise alone; however, beyond a daily intake of 1.6 g/kg body mass per day (up to as high as 2.2 g/kg/day), the additional effects of protein are greatly diminished." if you make a graph and put muscle built on the y axis and protein intake on the x-axis then it looks something like this.
You don't have to believe that this meta-analysis is 100% correct, it could be that after doing some research you find that it's actually lower or even higher, but my main point is that you shouldn't aim for 0.8g per kg of body weight and you definitely shouldn't promote it, it's harmful to veganism.
