There is a lot wrong with what you say (or maybe how you say it?) but it's your opinion. I'll express what is wrong with it in this list of points. Yes physical activity is linked to freedom and prosperity, but that is not the same statement as saying thinkers do not deserve freedom and prosperity. On one side of the coin you say something obviously true but on the other side of the coin you say something arbitrary, subjective, and the word deserve is imprecise, like justice.

1. Phonocentrism. I'm noticing a bias against introverts becoming a trend. Introverts care about freedom too even if it's expressed primarily in the intellectual domain, or over the Internet, because for a lot of people that is one of the last areas left where people can express themselves honestly and speak freely (free speech).
2. Income need not be attached to physical labor or activity. Mental or emotional labor also count. Stephan Hawking is an example, his physical body doesn't work but his brain does. He produces value with his thoughts. Other examples are programmers and mathematicians, who create value through intellectual gymnastics.
3. Your concept of "deserve" is arbitrary. And you are showing signs of bias. Is it not interacting with humans to communicate over Steemit, whether it's through a blog, or not? The concept of "deserve" is in my opinion overrated. And of course nothing is wrong with being physically active, and no one says people who are bloggers should only blog and do nothing else. You are right a developer or blogger isn't free in the traditional sense because they sacrifice "time" and brain power to produce quality code, but in order to escape the "prison" of the 9-5 might require becoming a blogger, and then from being a blogger a person can expand their sources of income and activities, but there has to be a starting point.

Diversified sources of income

I agree on this. We need diversified sources of income. But I guess I'm disagreeing with how you chose to express yourself. My point only is that compared to a 9-5 "bullshit" or "meaningless" job, blogging for a lot of people in toxic work environments is a massive level up. And for a lot of people, the computer or Internet is the first step to freedom, primarily because it's a place where a smart person can find an opportunity, but this isn't the same as encouraging people to "depend" on the computer, or Steemit, or any particular income stream. If a person can get income from many diverse sources, online, offline, of course that is more free than to only get income from the computer.

Relationship with money

In my opinion the purpose of money is as a means to an end. If it produces freedom then it's doing it's job. The Internet, Steemit, any piece of software, hardware, any ideology or religion, any politics, at least in my opinion, are means to achieving some end. From an ethical nihilist perspective, I cannot tell anyone what their meaning is or if there should be an end, but I do think if someone has the end of being free, then Steemit by design can help some people achieve that end. If Steemit doesn't liberate, if it's not a liberating technology, then it's not worth anything to people who work primarily for the actualization of freedom.
