He claimed that 3.7 million coins are lost, with the remaining coins being held on chains by early adopters.
All units are on the bitcoin blockchain and none of them are technically lost. What can be lost are the private keys that allow those coins to move. But no matter if the BTC is on an exchange, your mobile wallet, or a paper wallet, they are and will always be on the blockchain.
I believe the system should be changed such that each person is limited to holding a certain quantity of Bitcoin.

What a terrible idea. You want to punish those who believed in this economy more than you do or because they entered the market with more money than you or long before you...
Bitcoin is freedom and allowing you to make your own decisions. If those decisions include buying millions of coins, then that's your right. If you don't want whales to own so many coins, don't sell them cheaply on the market whenever some bad news about bitcoin gets posted. Tell your friends and everyone you know. It's an open market, but no one can buy your coins if you don't want to sell them. Look at me right now not selling you my coins because I don't want to.
Bitcoin doesn't have restrictions.
