Nobody can buy land in china, it is only leased from the government for up to 70 years for residential usage (less for other purposes). Calling the tofu-dreg building on top of this “owning a home” is disingenuous at best and deceitful at worst. Why do people buy homes anyway instead of renting? Because all other options to invest are even worse and it is literally their only option.
I hope you don’t tolerate how mega corps “sell” you shit like digital media or IoT devices only to later change the terms of sale and steal it back from you, because you never really owned it. Don’t tolerate the same shit if a government does it to you.
Batteries have one advantage over over supplies: extremely low noise. Even an good LDO will bump up the noise floor, and a cheap lcsc part will do so too. Plus you’s want a reasonably low dropout and quiescent current, which also increases price. Maybe 10ct in volume is reasonable for such a part - and yes, that will absolutely eat the margin
