Anything that is paying you bitcoin (or money that you can easily convert to bitcoin) isn't exactly stealing your freedom. But it is true that ownership of real estate is far from absolute & the risk of political instability exacerbates the problem. Currently it is still not particularly difficult to remain in good standing with govt. I agree that things could change rapidly (as covid demonstrated) & asset seizure is not an impossibility. I am sure that Bitcoin will perform better, but Bitcoin also probably isn't going to send you monthly payments, & cash flow can matter more than appreciation. If buying property that you can rent out allows you to quit working without dipping into your stack every month & maybe even still accumulate some during bear markets, then it might be setting you free. But keeping a high % of your wealth in Bitcoin & having a sailboat or a well maintained RV or some sort of backup/exit plan might serve as important forms of insurance so that your property can't be turned into actual chains.
I do find it extremely distasteful to have to pay anything to an organization that is clearly trying to enslave & destroy me, so I do fully appreciate your point.
