I don't understand what you meant by price makes Bitcoin more valuable, hope you don't mind making me understand what you meant by that or do you mean scarcity? However, the OP wasn't talking about what gets people's attracted to Bitcoin but what makes Bitcoin valuable so if your reason for mentioning price is cause people are adopting it cause it's becoming valuable then you're misunderstanding the point of discussion.
I think he is saying that Bitcoin is valuable because you can see it from the price and people are still buying at this price. A Bitcoin is worth $80k but you can see people are willing to buy it here, that is to tell you that even at this price, it's cheap to them and they think that in few years to come, the price will go higher not minding the amount they are spending but to an average person, that price might be expensive to them because they don't have it.
There are many reasons as to why Bitcoin is very valuable, but of all the ones, some are subjective. The most important and recognized of them all is the scarcity. Bitcoin has just 21m and the world is more than billions. If we compare the population of the world that recognizes investment, then the Bitcoin price is undervalue. If everyone decide to buy Bitcoin today, the price will be unbelievable.
