Regulations apply to people, not things or ideas. You should rephrase your question like this:

1) Should legal shops accepting Bitcoin adhere to certain regulations?
2) Should online exchanges adhere to certain regulations?
3) Should two individuals on the p2p network adhere to certain regulations before sending transactions?
4) Should individuals writing and deploying software that does automated Bitcoin transactions adhere to certain regulations?
5) Should ISPs and proxy servers that pass Bitcoin traffic through them adhere to certain regulations?

Etc.
