There’s a time limit of how long you get to own it, but it’s going to last past your lifetime anyways and how many people are living in generational homes? A leasehold land going back to the government also means new development to fit the new requirements of the city can be done in the future. (Not to mention this would prevent companies from holding large swath of lands forever and eventually become bigger than god)
wait so if you have another person travel to the other end of the wire, and do a time sync with consideration of time dilation to tell them to cut the wire 1hr after you turn on the power, will the device turn off after 1 year since it wouldn’t “know” the wire is cut until a year has passed?
