Same here but I had a much more cynical view of the oracle issue that it is by design aimed at eventual and total financial destruction of most participants. This cynicism were fueled further by the ideology that justified this for some great adoption that was promised even further back.

You can have decentralized systems but because monetary wealth accumulation is centralized by nature, and any decentralized system that introduces monetary accumulation and inflation reverts to a centralized state.

A good example of this is Bitcoin. Those with the most liquid currency (fiat) can buy more hardware that centralizes wealth. You simply cannot have an MLM scheme without a pyramid.
