I don't think dry ice may be used with current cryonics: It is indeed not
cold enough. I was thinking about a new cryonics technological generation
with cryoprotectors giving a full glassy state at dry ice temperature.

Well, a LN2 may indeed be built  near each cryonics facility. My dry ice
maker holds in a hand and cost less than $75. Now if there is plenty of
money, well, no problems with LN2. Please, dear rich cryonics organization,
could you put some money in fully reversible cryonics, I can give you a
good contact for that!

The real problem is not LN2 vs CO2: The first is the today working
technology, the second, a thinking about a possible technology. It may be
not alone nor the last. What is important at that level is keeping
thinking.
