What percentage of ETH staked in 2.0 will make the network secure? Right now only 4-5% is staked….

I have searched online for this answer but have trouble finding anything concrete. How does Ethereum plan on getting people to stake to secure the network? I’m finding it hard to believe that 2.0 will come anytime soon given how little people are interested in locking up their ETH funds. Is the lockup only temporary?
