I think that Vitalik&Co have no worries about such things because they realized a long time ago that they can do whatever they want without losing support. In addition, what beginners object to the most when it comes to BTC is the max supply, because they think that 21 million coins are too few, and that if there were more coins, they could buy them at a lower price.
In other words, the ETH team is proud that it has its own leader, that ETH is much cheaper than BTC and that there is no max supply - and for many it is therefore much easier to become the owner of 1 ETH than 1 BTC - because in the end it all comes down to numbers, right?
i really wish peeps could understand the max supply number is irrelevant as long as it never changes. if the were twice as many btc (42 million) it would cost 1/2 as much right now (~$34,000). so peeps buy twice as much for same price.
the base unit makes no difference. total supply could of been only one btc vs 21 million when you get down to it.
EDIT: dunno why peeps get hung up on a number. like when buying i dont look to buy a set amount of btc, i buy as much as i can, whatever the numbers are.
