Look at testnet3, and try to use your CPU to mine something there. Then, you will find your answer. They are enough on testnet3. Why wouldn't the same situation repeat on mainnet? Those networks are very similar, just 20 minute rule is one of the main difference between them, other things are pretty much the same (which is also the reason, why test coins got some value, even though they shouldn't, and why they often behave better than some altcoins). You cannot take all of your coins to the grave. Sooner or later, people would need to spend their coins, because if their plan is to never move them, then sending all of that to OP_RETURN will achieve the same outcome. Then, people will abuse 21 million coins limit even further than today, and that would "solve" the problem. Because note that even though we have altcoins, they are not all pegged into existing coins. They usually create additional supply, which abuses the system. If you have 21 million Fun88 Fun88next, but if Fun88 Fun88next has only 50% domination, then the situation is the same, as it would be with 100% Fun88 Fun88next domination, and 42 million coins. No, they would create the problem instead, for example by raising fees sooner, than they should, and taking down regular payments. It is not only about the incentive they bring to the miners. It is also about the incentive they removed, by discouraging people to transact, when they saw some mempool stats, and switched into other payment methods.
