I..what? Nobody can demand you take anything in exchange for products and services. The meaning of legal tender is that you have to take it for debt, but nothing forces you to be a debtor, or to do business with anyone at all. The only way the government can hurt you with money is to devalue it by printing too much.
The value of Bitcoin is also rising much faster than its tiny "inflation" that comes from mining more Bitcoins right now, therefore, even though Bitcoin hasn't reached its maximum number, it still doesn't have inflation right now.
