Many companies start in the "garage" and if you have privacy concerns, you can't use your home address as company address. This requires you to rent a spot in a coworking that allows you to use their address as company address. Also, you need to get a second phone.

Too many small inconveniences for a small unprofitable startup that you need to worry about, instead of focusing on finding product market fit.

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.

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 ?

One isn't a customer until they decided to get something from the company. But the website is available to everyone.

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

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

maybe your company is just home.

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?

The “a sane person wouldn’t do this” argument is really not that good.

Neither is the "criminals might abuse it so we should make things worse for everyone else" argument.
