AFAICS, Bitcoin has a deeply flawed long-term security model. Its block reward, which constitutes a subsidy for its security budget, halves every four years. Unless the halving of the security subsidy is made up for by additional transaction fees, Bitcoin's security decreases. Given that Bitcoin blocks are full - with only a little space left for further optimizations via SegWit adoption and Schnorr signatures - tran…
Bitcoin's security does not need to keep going up indefinitely. It will reach an equilibrium where tx fees will be paying for the entire security of the network. As the block size is capped, there will be a market for fees. Hard-forking to remove the block size limit would have profound consequences for the decentralized nature of bitcoin - arguably its most important characteristic.
I don't see any reasonable case for the prediction that Bitcoin's average transaction fee will reach those extreme highs.

I didn't say "remove". I said "raise".
