With respect to the massive engineering effort, and acknowledging you probably didn't even realize you were doing so, I have to point out that this is an example of the extremely distasteful emotional manipulation too often used by security-related companies, and it needs to stop. Advertisements with lines of the form, "Would you trust your family's safety with anything less," or, "Nothing is too good for your children's safety," contribute to the general paranoia of society, not to mention the gross misallocation of capital based on manipulation instead of merit.

Politics aside... it's your prerogative to buy or build any system you want. I was just clarifying why, in my personal opinion, if you really have a need for a security system, choosing a hobbyist project over a system built by a team of professionals is probably a bad idea (again, look for the article I linked before about how easy it is to "hack" into streaming baby monitors.)

More than I trust it to something that sends it over the internet to someone else's cloud over insecure channels, yes.

"trust your home" is somewhat misleading. The house won't fall down if the surveillance cameras are off. I've been in that home for years now without surveillance cameras and it's fine; I'd be a bit happier with some video feeds in various places but it will contribute to additional security: It's not all or nothing.

Also, wi-fi isn't the only or necessarily the best option to hook it up. I did mention that storage is harder that image capture now, but I believe that a Synology NAS or similar is the preferred approach. Multi-Terabyte HDs have gotten affordable.
