That data would absolutely be used to harm you eventually. It'd likely haunt you for the rest of your life.
The most innocent use of that data would result in you getting endless spam from the manufacturers of every item in your home letting you know about the latest model you should upgrade to, along with spam from every competitor telling you why their product should replace what you have. Companies you've never even heard of would suggest you buy their stuff just because you happen to have something in your home that is somewhat similar to something they offer.
Maybe the IRS gets their hands on that data and starts wondering how it is you've managed to afford what you have? Maybe you divorce and your ex's attorney uses that data against you because you forgot to list an asset or to demonstrate that you should have to pay more in alimony, or to paint you as being less fit for custody of your children. Maybe you have something in your home that matches something that was used in a crime and you become a suspect when you wouldn't have otherwise.
Maybe you have things in your home that others would find offensive and activists and extremists target you because of something you have. Scammers and thieves will use that data to target you more effectively. Physiological profiles will be updated based on what you own and how well you maintain your possessions. How sentimental are you? How much do brands and trends matter to you? What do your items say about your values? Those insights will be used by people looking to manipulate you and your views.
It could impact the prices you pay when you buy things, factor into whether or not you get employed at a job you want, and it wouldn't just be happening to you either, but to everyone else in your household including your children.
There's basically zero chance of that data helping you in any way and lots of ways it could end up being used against you without you even being aware of the cause. Your health insurance company isn't going to tell you that they raised your rates because the sporting equipment you kept in your garage made it look to an algorithm like you're more likely to get injured. You just see the higher bill. Everyone who gets their hands on that data will try to use in any and every way that they can to benefit themselves and that will usually be at your expense.
That's a lot of maybes. I think I'd take the trade, the same way I pay for Netflix even though it means they know what I'm watching, or sign up for the store card at the grocery store even though it means they know what I'm eating.
I'm willing to trade information about myself for goods and services.
There's no way to do anything in today's society without being surveilled and the data being collected never goes away. We all make choices on how much to we're okay with handing over knowing that it will all be used against us later. I'll leave the robots to you and just hire a few young men to do the job. I'll sleep better knowing that at least in this case, I won't face negative repercussions for the rest of my life as a result.
The Constitution and the principles of my country are perfectly aligned with adults entering into a mutually agreed business transaction. They’re aligned with a company offering to sell me a service with a given price, and where part of their upside is retaining data about me.
autoexec’s reply in a parallel thread is a strong case for why somebody might view the impact of that data retention as too costly to be worth using such a service. And that’s why nobody is forced to hire data-collecting robot movers. But under the principles and freedoms of my county, companies are allowed to make the offer.
Rereading the post in question, I'm not so sure that I'd be afraid of "theft of my personal data" so much as "a plan for theft of my personal possessions." A map of my house with an inventory of my possessions would mean a lot to thieves who wanted to hit targets quickly and optimize their spree for a value-to-weight ratio. That kind of data could make organized burglary very profitable.
The overlap of "the entities that carry out data breaches on digital entities" and "the people who break into your house to steal stuff" is not really well correlated. This is for a variety of reasons, but the most boring is that hacking websites is way smoother when you're a faceless entity far from any kind of jurisdiction, and breaking into somebody's house is something you need boots-on-ground for.
Scammers and thieves are using data brokers more and more all the time. They already buy up lists of rich elderly people, lists of people with dementia, and lists of people with low IQs or poor educations who are often easier to trick out of their cash.
Most criminals breaking into houses aren't buying up targeted lists of likely victims from data brokers yet, but it's effective so you should expect that the number of criminals turning to those resources will only increase.
