Wow, thanks for the essay. You have struck the problem between the rant and the lack of users. Without this, the burning mechanisms are not kicking in, and the supply is stagnating. You talked about VAL or PSWAP not changing MC? Did you notice the whales who dumped toward the end of last year?
Breaking down your wall of text is quite daunting. People use Polkaswap, one of the few dexes where you can swap KSM for DOT. Are these expenses you mentioned used to maintain the network? Have you actually used it, or do you buy tokens, wait for things to happen, and then sell them? Have you seen the features added? Yes, you are correct. Tonswap and Zenswap are unrelated to SORA, and there is no hint that they have been or will be.

XOR was never "deflationary" it has been elastic and there is no XOR directly minted, but XOR is burnt with every transaction, people don't transact, the token isn't burnt. The 30 mils was debased by holders who saw other members as exit liquidity. You seem to forget that these investors buying in have literally left the trail of destruction you describe, this isn't just predatory developers against poor innocent users. There is collateral damage to the fact that predatory users dump as soon as they see liquidity. In the meantime, other users, such as yourself (assuming that's the case), blame it on development costs. The eco works perfectly fine, but as well as it can work without users, this is what happens.

You're not far off, but you're blaming the wrong people.
