Wow, that is a phenomenal question, and I'm sure others will chime in as well. It's a difficult question to attack since crypto-related legislation is evolving at an increasing pace.
However, the first thing that comes to mind is if biometric scanning were to ever become a requirement for accessing certain forms of VR. As far as I am aware that is not yet a requirement, but if it ever comes to be then the only advice I could offer at this point would be to steer clear of those particular services. This is why some forms of crypto ATM's are immediately discounted by Monero community members, and I see the same attitude carrying over to any other theoretical implantation of such identification methods.
Additionally, if future services employ a know your customer (KYC) approach to identifying users, then that too would be up to each user's level of comfort. A relevant case would be the crypto exchange Poloniex's sudden statement last year, requiring that all customers provide several tiers of personal information, thus cutting off their fund withdrawal ability to whatever tier they had reached (I believe the first was to provide just a first and last name, which could conceivably be faked). Should this come up in the future, again, this would depend on each unique user's preferences, but it may still be possible to use a false alias and retain access to the service as is possible with Poloniex's first layer of identification.
This is just what's popped into my mind, and I'd be delighted of others had additional input.
