Well yes, of course, it's right now thus "not yet you can't", no one is questioning that companies exist offering this service the problems already mentioned still exist and it's still a long shot at the moment. Kinda moot if it works out for some improved process for people undergoing it in 100 year's time as that doesn't necessarily mean dead people frozen using the current tech (and with the damage caused etc..) will be able to be revived then.
So will they be at this level in 100 years time - obviously not. But there's a big difference re: some 100 years in the future, able to freeze and revive people tech vs being able to undo what has already been done in the present now. We might well have solved ageing by then, doesn't necessarily mean we can bring people back who are currently frozen.
