Hey here are my responses

1. I disagree, all 'unsuccessful' nodes will become standby block producers and will receive some compensation (details are being finalized) and as voting happens every 2.5 minutes there will always be a chance to get voted in.

2. EOS tokens are not mined and BP's will not be able to sell them straight away. Similar to how Steem Power works on this platform. Also, you are not including the benefits of keeping your EOS in your wallets such as airdrops and the ability to rent tokens and RAM.

3. Yes, eth is a good platform but is suffering from serious scalability issues remember crypto kittens taking down the entire​ network, that was just 1 dApp. There will always be competition in the free market which is a good thing for all of us but that has no negative​connotations​s on EOS. Agreed, if the launch fails the price will drop but even if the launch is successful the price will drop, we see this with all crypto's. Again the allure of airdrops around the time of the launch will keep those who truly ​believe​ in the platform in the game. eosDAC completed there 1-1 airdrop​ and it has turned out to be very profitable so far.

4. You are very wrong here. For a start,​ the testnet is producing 1000 tps (500 per block, 2 blocks per second) and there is no reason to think that the mainnet will not do the same.
