I would argue otherwise.
A bond frees up money that wasn't doing anything. POS locks up money so it can't do anything.

When a company issues bonds it intends to use the cash to grow the company. The buyers have cash
that was just sitting there so they buy bonds to earn interest. It prevents cash from stagnating.
POS only looks like a bond from the buyer (staker) side, it's a deposit that earns interest. There's no
more economic benefit than putting cash in a mattress where it stagnates.
