If anyone is interested in staking their eth to validate blocks, they can delegate their stakes to staking pools and still get a share in the rewards that the staking pool would get. There are several pools for eth 2.0 launchpad staking already and there would be even more pools that would cater for the average investor. Pos is one of the best things that would happen to ethereum. If it launches successfully it would go far to ensure that tx fees and low too. Now it's just too centralized and only the big boys are allowed to own and participate in mining farms.
