I find the math on security of the #bitcoin network really relaxing.
If we consider today the network is safe, then in the future, without a miner reward, the fees would need to be around $50 per transaction.
That is incredibly cheap to run a global economy.
If you take current providers of banking and payment rails taking about 2% that means that transactions over $2500 will be made on chain, everything else will be #Lightning .
This is a good number for business management and general household management.
Math says we already won.
