I agree. Well, I can only say that it depends on the person on what that person will decide. Let's say about you as the example, you said you use it for dca and for personal use. Another example, let's say it's me as an example which I use Bitcoin for saving/investment/holding and not using it to buy or something like that. In other words, it depends on the person who owns some bitcoin wether they use it for both saving and spending or other things that it can be use for.
It is a personal choice and that's what OP was asking not sure why he/she is so concerned about it but maybe he wants to know what we are doing, either we are spending our btc to buy things or we are too possessive with it that we don't want to let it go. I am not so possessive as I do not want to let it go but I have to haha because at some point I have to sell or the price is too good for me.
Bitcoin was made as a tool for spending, a decentralized asset to be used for digital payment without the need of middlemen and it is being used for that and for saving as well.
