Crypto is more than store of value whether you are a trader, entrepreneur, techie and more. The reason why crypto has got this far is largely that of people rallying behind it due to their interest. Now, the individual reasons why people are involved differ but the power of the community cannot be ignored. Decentralization weakens former powers grip on us (govt, banks).

If you are wooried about GDPR or similar legislations I think blockchain can be extremely helpful. Personal data (pII) cannot be stored on the chain because general data protection clearly calls for data erasure. Former CRUD (create, read, update, delete) operations must turn to CRAB(create, retrieve, append, burn). In order to be privacy law compliant consent must be stored off chain and interact w blockchain via oracles. I personally think current GDPR rules are very heavy handed it only makes google and facebook even bigger monopolies.
