that nobody is interested in any serious stuff being done remotely

From experience, I can say that this is simply not true. Obviously you have to get the right channels to find interesting assignments, and be able to build trust (have a good portfolio/CV) but a blanket statement like yours doesn't make sense.

BTW, even if it pays somewhat less than having a full-time corporate "career", some people just like a more adventurous life than just sitting in an office all day. Now, and not at some non-descript time in the future when "retiring". It might not be for you but don't pass value judgements.
