I am going to explain why tail emission is an attack on the Bitcoin core principles and why it would spell the end of Bitcoin as we know it, if ever implemented in any serious kind of way.
Bitcoin Core Dev Peter Todd, came up with the idea of taxing Bitcoin holders on their money to pay miners more for security, like we don't already pay miners in fees and there wasn't already a fee-market incentive for miners to plug in their machines or unplug when unprofitable, again another attacker trying to address a none issue with fake solutions with fear. Let me explain farther below.
Bitcoin works because of the 21M hard cap removing this would spell the end of it as hard money, tail emission is like making a small hole in the bottom of dam that will eventually grow big and make cracks until the dam falls. Why is this an attack?
Well, most people who buy bitcoin are buying it because it has a hard cap of 21million that nobody can change, that's the reason why I started paying attention to Bitcoin in the first place, so removing that already turn off a lot of us as we start pricing in future taxes or increase in the money supply, not only that, the other problem is "who has the right to print the money this time and every other time in the future? Peter said it's for security, well I want remind him that there is a difficulty adjustment in Bitcoin that always look for free market equilibrium, when hashrate is too high it goes up when it's too low difficulty goes down to incentivize mining, and if he is concern about the halving lowering rewards in bitcoin terms well again SATs get more valuable overtime so any amount of transaction fee will support the network even when all the 21M coins are mined. The issue here is if we start printing more SATs to devalue the Bitcoin overall market cap, Bitcoin price falls miners get paid less valuable money therefore less miners are incentivized to secure the network, so it would actually break Bitcoin, but let address his other arguments.
Peter also points out that the miners will collude to attack the network in a potential future, "future he can't even predict". Here again another strawman argument, asking for power so he can protect you in a future attack that he doesn't even understand if possible or not. Miners don't control the network, they may decide to pay a bunch of devs to introduce a code that benefits them but what are the chances the code ever get into everyone else node? He said well do the math it's good to do the math.
Ok, I am going to do the math, I am sure in 10 to 100 years from now 100 of countries plus millions of businesses plus billions of people will want to send some bitcoin utxo on-chain, if each block contains 5,000 to 7,000 transactions in average of 1000Sats fee each then that's an equivalent block reward of 5M to 7M SATs each, that's $500K minimum at $10Million bitcoin. So you see transaction fees can easily support the network in the future without any changes to Bitcoin. But again these people will always find an excuse to convince you why they need to print money for free that everone else have to work for, so don't fall for it.
Lastly, I want to point out that the Bitcoin limit is not a number you can change just like that because it's based on time, that's why Satoshi said he had to be very careful with the 21M number because once the network starts you can't go back and change it, you would have to go back in time Jan 3rd, 2009 to change the genesis block to change it, this core design principle is set in stone for the rest of Bitcoin lifetime and we would like to keep it that way.
