1) Why do you think a revival will remain prohibitively expensive forever?

2) If you've got no living relatives, then one reason for revival could be commercial. A company could simply revive you for a certain cost and then you have to pay them back in the long run.

The latter couldn't even be argued to be a forced contract without consent. Considering that you were taking the trouble of freezing yourself, it can safely be assumed that you'd be more than happy and willing to pay for the cost of your revival in the same way you'd pay off any ordinary debt. Hell, I should own that company.
