Because you appear to be a complete morality vacuum. You have no sympathy for the many pensioners who have not benefited from the rising property prices because they've never owned a home, or those who haven't worked all their lives because of societal pressures, disabilities, or any other reason.
You don't care about the free will of other people - you only see how you could benefit if they were forced out of their homes into (non-existent) retirement properties.
You have no consideration for those who have worked hard all their lives and struggled to make ends meet or pay into large pension funds because they're poorly paid, on zero hours contracts or are disadvantaged in other ways, even though these low paid jobs are often essential to society. You only care about how much you are paying out.
I'm not in any of the demographics above, fwiw - but I can see how people end up failing to make provisions for their old age through no fault of their own, and I have sympathy for these people. Protecting those who cannot help themselves is what the state and taxation is for, and it's a privilege to live in a country which values that, and to pay into that system. Those who can afford to pay higher rate tax should be glad to do so.
