just to outline this fictitious would you rather, you rich enough to retire cryogenic preservation is perfect. you could live out the rest of your life in retirement and see the world evolve “like god intended”, or you can adopt cryogenic lifestyle where you freeze yourself for however long you want and stay thawed for however long you want but your still a human with natural human lifespan so you will eventually die.
of course contingencies are allowed if you think something cataclysmic will happened you can be dethawed abruptly and considering future medicines to extend your lifespan is allowed
Even if I wanted to be frozen, there is no point. One would have no guarantees that you wouldn’t just be thawed and disposed later so the company can sell more stasis slots. Or if they decide to even try to keep their word, they could maintain your stasis so badly that you would die from that or maybe thaw partially occasionally or something. Unless you are billionaire and could afford somekind of insurance that makes sure nothing happens to you, there would be absolutely nothing protecting you.
And even if everything went according to plan, society could collapse in such way maintaining the stasis could become impossible due to lack of resources.
