The initial seasteads will not focus on moving too much. There have been some designs where each unit is small enough to be loaded onto a tanker and moved (for long distances) or for short distances wait for a calm day and use a tug type of boat to pull it.
only rich people can afford this seasteads. now, blockchain is making a big impact and even ordinary users can partially own it. but i think in the long run, small time investors can have only those tokens but not really owning a seastead. they are just mere holders of tokens. but why not, just the idea of having such kind of ownership might do you good, mentally.
There will be a wide range of people on the seastead, some renting, some there for vacation, some owning. At the very least you can use your varyon to go on a vacation to visit the seastead and meet the interesting people that will be living there.
Im sure there will be people who will see buying seasted as an investment,and they will rent the place,so you wont have to be extremely rich to experience something like this.
Is there any blockchain project that is into lending and renting properties? Might be a potential partner if we get to the point where people that own a property on the seasted want to rent it
