I like those bitcoin debit cards also... but yes, they only allow for very small transactions unverified. There is no way around it as far as I can tell.
All these "money transactions" need to be verified by law to avoid money laundering and criminal activity. Bitcoin is too well known for that by now.
I would accumulate the bitcoins, never convert them to fiat and hope you find that person that will sell their house or car to you and accept bitcoins for it. Technically you probably will need to report it on your taxes as "barter" but who knows about it if you don't tell?
To be honest I find those bitcoin debit cards pretty useless, they are of no actual use for now. And all of them claim that their debit cards work worldwide in all ATMS. anybody here who actually uses it and has tried it? I don't really understand why would anybody cash out their bitcoins, especially through ATMs. I'd never cash out my bitcoins man, I'd diversify my trades but not cash shit out.
