I think today, most of governments income comes from newly printed money, it is magnitudes larger than their tax income, so it is very strange they still want to make lots of paper work and collect those miserable amount of tax income
That's certainly true, mate. But governments (and central banks) are greedy and they want to take advantage of a revolutionary tech such as crypto and Blockchain for their own benefit. As long as they're able to tax crypto out of people's "pockets", the industry will see the "green light" for its growth within the mainstream world.
Now, imagine if Bitcoin and other cryptocurrencies across the market were completely untraceable. It would be nearly impossible for governments to be able to tax crypto effectively from everyday people. Still though, the mere fact that every single cryptocurrency is being traded on centralized exchanges has a lot to say over government's prominence within the Blockchain industry. After all, it is these same centralized exchanges which makes governments' life easier by enforcing ID verification to their customers. This allows governments to tax crypto even if privacy coins are used for trading on an exchange. With decentralized solutions, taxing crypto would be a thing of the past. The main issue is that decentralized exchanges have lesser liquidity than centralized ones. Using both a non-custodial mixer and a decentralized exchange would allow a person to remain "under the radar" for a very long time.
Nonetheless, it's our obligation to pay taxes in order to avoid facing jail time. I know this goes against crypto's value proposition of "eliminating the middleman", but this is the path crypto has taken lately. The way I see it, crypto is heading more towards centralization and manipulation than I've ever imagined. As long as big players like Binance and Bitmain dominate the industry, there's the risk of centralization which gives governments an advantage over one's crypto funds. That's why people need to use decentralized services more thoroughly in order to prevent crypto from being manipulated (sort of) at will. Until then, crypto will be forced to follow government regulations or its growth will be stifled within the mainstream world. Just my opinion
