It's not obtuse regulation, it's explicitly by design. In most places in the US, you cannot operate a business in a residential area that serves the public. Businesses that do not serve the public (like a tech startup or someone working from home) are fine. Ice cream trucks are also not allowed unless you have a proper business license / permit.

A mile on a bike should take about 5 minutes too.
Why would the democratic party want democracy? The people in positions of power in the party got a lot of great fundraising this cycle, and they'll be able to use the threat of this incoming disaster to raise even more!
Do Americans really believe they’ll be able to get their pet monster under control once they genocide the entire Middle East?
I don't think any Americans who truly support this think further than the next quarter of Raytheon profits.

They exist, but are more niche. See, for example, the Savage takedown rifle that shoots 22lr / 410 shotgun shells. https://www.savagearms.com/content?p=firearms&a=product_summary&s=22440
Clearly it's geared towards more of a survivalist/bug-out type scenario, where you might need the 22lr for a squirrel and a 410 for game more substantial.
Obviously several revolver calibers are multi-use too - 357 mag revolvers can all shoot 38 special ammo, for example. Shotguns are also very versatile, letting you shoot slugs/buckshot/birdshot/whatever, all out of the same tube.
I think the increase in ballistic technology has basically made multi-caliber guns fairly obsolete, but I'm no expert. But if you're carrying something pistol-sized like the article shows, I would imagine you would benefit mostly from just more magazines of 9mm, rather than trying to make a clunky shotgun attachment for a pistol, leading to (1) more complexity in the pistol, meaning more possibilities of something going wrong, (2) need to carry multiple calibers, and (3) more difficulty in training to use both calibers effectively out of the same pistol (i.e. hold it like this for 22lr, hold it like this for 44 magnum).
If you have a business like a law firm where it is VERY IMPORTANT that a PDF has certain qualities, free tools for PDF creation can be a big gamble, especially if you have to open a PDF that someone else has created and do changes to it. And the cost is pretty trivial compared to the cost of messing up.
