France had a aggressive enforcement policy to 1924, when its former Entente partners failed to support France. The Coolidge administration in the US was particularly hypocritical, willing to send US Marines and Army Regiments to China, but actually encouraging the Germans to resist the Ruhr occupation 1923-24. It was this failure of France former partners, leaving France politically isolated vis German policy. This lack of international support led to the Frances defense policy in the 1930s.
Because of the impact it had on the recovery of the European and with it global economy. France didn't care because they were getting paid anyway through enforcement, so it didn't hurt them, but the UK suffered and through that the US ability to profit from trade and get their unsecured 1917-19 loans paid back, while of course Germany too was viewed as a trade partner worth getting back on it's feet. Plus the US never supported the ToV, so had active interest in opposing enforcement.
There was little hypocritical about it, they had specific interests with Germany that were better served by France not wrecking their economy. France too was only looking out for itself, which is why it was willing to spit in the eye of it's allies to enforce the ToV regardless of the impact on the regional economy due to Germany's inability to pay. French defense policy of the 1930s was very myopic and paid little attention to the wider impact it would have, such as bankrupting the Creditanstalt in Vienna and worsening the Great Depression:

The resulting economic impact forced France into a defensive posture, because they were broke and there were few threats on the horizon due to the global economic crisis causing military cuts everywhere.
Would the French people support such a bold and potentially aggressive action like opposing the re-militarization? Or could it be a good thing for France? France was pretty stuck in a rut after WWI right so could being aggressive and coming out on top because of it spur the French back into a more proactive foreign policy?
Springing off what I wrote above, France couldn't because of the budget crisis they were in as a result of their flawed economic policy and the Great Depression causing insolvency. In fact German intelligence had picked up on that, which is the major reason Hitler even risked remilitarization; it was known that the French couldn't even afford to mobilize due to the budget/banking crisis, which got France, in part
(the other was an agreement with the US and Britain), to abandon the gold standard thereafter and start liquidating their gold stocks to finance rearmament:
