you can't expect everybody to take care of you, and you can't make your existance a problem for everybody else, so you must be doing something productive or something that contributes to others in some way, or, if you choose to live without material possessions and without a home, but can survive off of nature, or even off of trash or whatever, and this is what makes you happy and it's the life you choose to live, then that's fine, so long as you are supporting yourself, and not taking from or burdening others.
You can even be a researcher or a chemist and live in a nice house and own nice things while still supporting yourself, while "dropping out", taking psychedelics, and remaining free, I've made it work anyway...
Look at terence McKenna, a writer who survived off of the ideas he formed while traveling the globe and consuming psychedelics, he was well educated, he attended college, he could have easily settled into any number of mainstream caterers, yet he found a way to fully support himself, and live well, by doing the things he loved, by publishing books, or holding lectures, he even dabbled with drug smuggling in his early days, regardless, this is a perfect example of being able to "drop out", being able to do what it is you want to do, without ever having to depend on a soul crushing job, or a "boss", or a culture which has no value for the individual and cares not for the lives they waste...
