I half disagree with you

Regulation does not have to be costly at all. I've helped companies get regulation and it cost them less than what most ICOs invest in marketing. So if done well it does not have to be a death sentence to the underdogs. Though the "if done well" part is the one I'm worried about

That's why it's something that we're addressing in our company. Because building it up correctly is SO important.
What I'm talking about is sets of regulations imposed by governments and banks. Once those hit the crypto world, we can forget about the super gains like Stratis and Monero. Look at the USA, now American citizens are 'protected' from having 10x gains through ICO - a good example of regulations!
I am also talking about regulations imposed by governments (the only regulations banks impose are imposed on them) are not always costly, and I am saying this from experience. I advise a company that helps companies get regulated in many jurisdictions. Regulations don't HAVE to be costly nor do they HAVE to limit potential gains. The fact that some regulations do doesn't mean that it has to be this way.
So should there be regulations? Absolutely. Right now, it's too much like the wild west. But as I've said - smart ones. Not idiotic ones that do nothing to actually achieve something meaningful.
