This is addressed in the original white paper. In a world where BTC is valued at 1M USD/coin you’d also expect a decent amount of day to day usage. Miners could still make decent profits based on transaction fees just from confirming blocks even once the Coinbase rewards stop. I’m not saying that’s currently the case, but that is the design. Also if miners are making a profit off let’s say $40k/coin and the price goes down to 30, yet there’s still a profit for some miners, how exactly does that become unsustainable?

Miners could make a profit at $1/coin. The issue is that profit comes from somewhere. And that somewhere is new money being put into BTC. Hence, BTC is negative cashflow.

Help me here. All databases are negative cashflow. They only 'cost', don't generate 'revenue' by themselves. This is true of ACH mechanism to transfer funds from one bank account to another. Does that make USD negative cashflow? Does the cost of maintaining this ACH system affect the price of USD v/s GBP?

The value provided by a database such as BTC is that it provides a record of 'who owns what at what point of time in history'. I can argue separately about why the 'immutability' of this database itself is a value created by Bitcoin, for which holders can be willing to pay premium for.

Miners earn profit if Operating Costs > $ value of (Transaction Fees + BTC mined). Over a long enough timeline, Fees + BTC mined will ~~ operating costs of the rig. If not, more miners will continue to see economic opportunity, and keep joining the miner pool till that equation is balanced.

The other source of BTC value going up need not be more demand for it, let's say over next 12 months. The ~6% inflation could show up there too.

What am I missing?

Profit comes when their operating costs are less than the take home from any transaction fees and Coinbase rewards they’ve collected in the same period. It’s not a direct function of liquidity entering the system. It’s true that rising prices from new cash flow means more profit for miners, but that doesn’t imply the opposite. The price could stay constant for the next 100 years and miners that have found a way to remain profitable within that price point would be fine.

Citation needed.

(I don’t see why this should be true at all. If anything I’d intuitively think the opposite: If gold were $1MM/oz I don’t think people would be using it to buy groceries… Unless you’re directly talking about hyperinflation where $1MM isn’t worth a loaf of bread any more.)

is the day to day usage of bitcoin currently increasing in proportion to coin price? it seems entirely possible that the price could get very high solely as a speculative investment. in which case, you would still need additional investment money coming in
