Paywalls are walled gardens even if I would want to use them I cant because the internet is global but paywalls are not.
Beside that its not feasible as paywalls are usually a subscription, the average user would need to have 10-100 subscriptions to cover their browsing habit. Not only is this way to expensive its also completely impractical. And it would self inflict a incentive to not leave your subscription bubble.
Micropayment make it possible that I can pay without subscription without giving my personal data and without some absurd premium price that is justified by the fact that I could consume other stuff for the rest of the month/year which I likely dont want.
>But different sorts of fraud are imaginable
Sure and we find solutions for these. Unlike with ads everyone should be onboard blocking and fighting the fraud. with ads however thous who dont commit it can still profit from it.
>If you do confirm every single payment that's probably unacceptable
But there are solutions for these problems. Lets say you want to watch a youtube video, it could be free for the first 10% and then ask you to confirm payment.
Then it steams payment as you watch so if you stop halfway trough you only paid half the price.
>Or the copyright problem already seen with NFTs
There is no such NFT copyright problem its made up nonsense.
People just dont understand what they buy usually a public price of art. So its already released when sold and people can copy or store it however they want. Its worthless just like an MP3 file of a radio hit is worthless the rights on that track however may not be worthless if the owner know how to make money from it.
>copy someone else's pages, charge for access to them.
Already possible now. Micropayments does not change anything here. People steal stuff and "sell" it. There is no technical solution for this problem.
