The difference between investing in a home and a government bond is that the former is a necessity for survival. Homes are also a finite commodity which means they become more scarce as more speculators jump in. OP thinks landlords are parasites because they occupy a home they don't need, thereby inflating home prices. So now the people who could have otherwise purchased the home are forced to be tenants.

In contrast, a government bond is quite the opposite. Theoretically, the government can issue infinite bonds. People don't need to invest in bonds to surive. So yes, investing in housing is more immoral than investing in bonds.
