When I see an imprint and see that it's a home address, I have no problems with that. It lets me know that this person is either just getting started or simply doesn't want to grow into a bigger company, probably because he/she has a real job, which are both great things, but if they scam me, I know where to contact them.

Why would I randomly show up at their house and ring their bell?

Why do you think the company needs its right to privacy but the customers that deal with that company don't need the right to know who they're dealing with ?

For your startup, aren't you setting up your DNS, webhosting, etc? aren't these small inconveniences that you're doing instead of "focusing on finding product market fit" ?

Each company, nay, each person has to do some amount of "paperwork" in order to create society that functions. Why should your startup admin be easier then my filling of personal taxes ?

At least here in Germany, you shouldn't use your home address for your business at all, because of Tax obligations, at least when you are not renting.

Because if you want to move your business later, when it grows, the tax office will regard your home as part of the business. Things will get complicated that way.

Dont start a company if you are so poor you cant afford a postbox.

Disagree with everything you said. These are all self-created non-issues.
