Blueskull,
It's not about me personally being "worth hacking" I have no delusions of my own importance on the world stage.
The problem is when it's done as a matter of course, and then access to all the data is slopped around any government agencies that think they might want to use it, then all the captured data becomes a massive target for all sorts of other groups of people. It becomes something that is worth stealing for many reasons. Soon enough someone will stick in a big straw and slurp it all up.
In a business/work related angle, sure the NSA and border protection don't care if I've designed a widget with x,y,z features.
But when criminal orgs eventually get their hands on all the captured data, you can bet a competitor can pay someone to search for anything related to my customer's name, find all my docs and the captured data, and then get all the trade secrets they want. This is particularly a problem for me, as I have non disclosure agreements in my contracts, and so having my data harvested by incompetently managed government programs can put me in breach of contract...
Or how about I annoy someone in my day to day life, so they go to this black market data harvester and pay to get any information on me that can be found. then they go through all my emails, receipts, bank details, and use that to attack me?
Or how about I'm a married christian family man who happens to have a gay lover on the side (seems to be a pretty common thing, eh?) and I organise to meet him by emails a few times and we talk about our relationship and our feelings for each other? the government wouldn't care (well, not till president pence kicks into high gear) but when the data ends up in other hands it can be mined to expose huge groups of people like this to extreme blackmail. And depending on what kind of job someone like this has, those results could be massive.
Or how about by some miracle the huge pile of insanely valuable information never gets hacked, but one day the government decides to search all emails and web history for any kind of "flags" and then puts people on a blacklist or prison, depending on what they might have spoken about or someone might have looked at on one of their devices?
Or how about the data capture process doesn't just capture data, but opens up a big back door in your device which never gets shut, and then lets someone who knows what to trawl for go into devices and grab all that data from anyone in future and build up their own database in parallel?
Right now companies like google and apple already hold most of this kind of information, and generally, they have been mostly good at protecting it because their business relies on that. They do provide info to specific agencies on specific accounts when requested, but generally government doesn't hold that much data on everyone's business... Government is full of incompetents who have nothing to lose over the breach of a dataset like this. And so it is way more likely to be breached on a massive scale than google or apple.
