You're using apps to change numbers associated with digital addresses, but claiming to move around something.
In traditional banking systems, you are also using some bank's app "to change numbers associated with digital addresses". And they are also "claiming to move around something". And it works, until it doesn't, and suddenly, there is a need of "second bailout for banks". That's why Bitcoin was invented: we don't need "bailouts", because coins are simply worth more or less, depending on the outside world.
Does anyone bother checking the trust / feedback of people before replying to their posts.
No, because people are paid, based on the number of posts they write. So, by writing an obvious reply, that "2+2=4", you can fill your quota easier on such topics.
In traditional banking systems you are using bank apps to change the ownership of an asset, with numbers representing its quantity. In the cryptocurrency systems you're updating logs of pyramid-style schemes by changing numbers. There's no asset involved. Thinking that an activity log of a pyramid scheme is an alternative to an asset is craziness of a high order.
