Yes.. I think part of the community would be really against accepting advertisement, but we have to see Steemit as a business.

Those people have no business interfering when adults talk real business. Unless they're ready to pay up to cover the infrastructure costs themselves, they should shut up.

Ideally the Blockchain and community could sustain itself by constantly adding value and keeping prices at a certain level. But accepting ads could be a great way to transition to that stage. It could be an interim solution.

You can add value all you want but getting money out of it is the crux of the matter here. Advertisements or other type of paid promotion, subscriptions and tipping are the only viable long-term solution. Relying on a game of greater fools can work for while but it will end in a pile of rubble eventually.

Unless of course Steemians would be incentivized for allowing ads in their feed. Like the Brave browser does. A fair revenue share - then everyone would be for it, I guess :)

That, and nothing less or nothing more, is what makes a blockchain-based solution like Steem unique. Distribution is guaranteed to be safe from the arbitrary dictates of a central authority. The way to monetize content is exactly the same as with traditional social networks. The only differences are in distribution and governance.
