No Bitcoin miner has a right to be profitable, no matter how big or small their operation. Instead they have the opportunity to be profitable if they manage their operation wisely. The difficulty adjustment helps to ensure this is the case.

One of my big issues with the OP_RETURN debates is this idea that today’s block reward itself is somehow not enough to incentivize miners, and the underlying assumption that demand for block space with never increase again unless all manner of shitcoinery is allowed to infiltrate network activity.

The block reward is substantial and will be for many years to come. No miner has a RIGHT to profit, as they are TOO BIG TO FAIL. All miners have opportunity to achieve it, and if some fail and more smaller ones spring up along the way as they see a chance for profit, then that’s a good thing.

I can’t help but assume that short-term self-serving interests are driving those who want to allow for more arbitrary storage on Bitcoin’s blockchain.
