Yes, they absolutely can. Like with any surveillance technology, there are things you can do to obfuscate your patterns, but that doesn't mean that a broad rollout of the technology won't have a negative privacy impact on most customers.
It’s not obfuscation, if you are concerned about privacy. You can completely hide your usage patterns with a battery or solar/wind generation. Are you honesty making the point that: knowing you used 5 units of power in 1 month (where someone has to walk onto your property and read a number, as is the case in most dumb metered scenarios) is less of a privacy concern than knowing you used .3 of unit of power in the las…
Personally, I think so for most people. But that depends on how much privacy your property provides from pedestrians and where your meter is located.
However, that is orthogonal to the debate since there are other options. Some places allow self reporting and Automated Meter Reading can be done without a smart meter that reports live power usage.
I am unsure why you are so vested in arguing that nobody has a legitimate reason to be concerned about this. It is fine if it doesn't bother you, but it is really necessary to paint those with different concerns as irrational?
